What’s new

Facet campaigns are here. You can now apply one set of facet rules — slotting and/or hiding facet groups and options — to many results pages at once, instead of configuring each page separately.

A single facet campaign can target a mix of:

• Search queries (e.g. “denim”, “running shoes”, “ground coffee”)
• Browse category pages (e.g. Shoes, Coffee, Skincare)
• Facet pages (e.g. “Size 7” Shoes, “Straight Leg” Denim)
• Collections (e.g. “Viral Hits”, “Kid’s Summer Shoes”)

Think of it as Searchandising Campaigns, but for facets: one place to define the order and visibility of your filters across a whole group of related pages.

Each facet campaign currently supports up to 100 queries and 100 browse/facet/collection pages (combined).

Why it matters

 Previously, keeping filters tidy and consistent meant repeating the same facet rules on every individual page:

• Hiding niche facet groups (like “Heel height”) on categories where they barely apply
• Reordering key facets (like “Brand” or “Sale”) across long trees of categories and collections
• Repeating the same updates every time your strategy changes

With facet campaigns, you:

• Configure once, reuse everywhere. Define facet ordering and visibility in a single campaign and apply it to all related pages.
• Keep filtering experiences clean. Hide facet groups and options that only matter to a tiny subset of items so shoppers aren’t scrolling through noisy filters.
• Stay consistent across parent and child PLPs. Align the filtering experience across a parent category (e.g., “Shoes”) and its children (e.g., “Boots”, “Heels”, “Sneakers”) without micromanaging each page.
• Move faster when strategy changes. Update a single campaign instead of revisiting dozens of PLPs when you change priorities (e.g. pushing “Sale” or your own brand to the top).

Example workflows

• Tidy up irrelevant facets at scale. A retailer only wants to show Heel height on women’s boots and heels—not on sneakers, kids’ sandals, or men’s trainers. They create a facet campaign, attach Shoes, Athletic Shoes, and Kid’s Summer Shoes pages and collections, and hide “Heel height” once. All included pages inherit the same tidy filter set.
• Promote own brand across a family of pages. A beauty retailer wants their own brand to appear first in the Brand facet on search results, “Makeup” categories, and “Viral Hits” collections. They add these contexts into a single facet campaign and slot their brand option to position #1—no need to repeat the rule per page.
• Align parent and child categories. A fashion retailer wants a consistent set of filters across Denim, Denim > Straight Leg, and Denim > Wide Leg, but with fewer facets on the narrower children pages. They build a facet campaign for all denim-related pages, then hide niche facet groups from specific sub-pages while keeping core filters aligned.
• Seasonal or promo-focused filtering. During peak season, a merchandiser wants the Sale, New in, and Sustainability facets to rank higher across key search queries, categories, and promo collections. They create a campaign, slot those facets near the top across all relevant contexts, and adjust positions from a single configuration when the season changes.

Constructor continues to make shopper discovery smarter and more intuitive. Our latest update introduces Discoverable Collection Items, a lightweight, API-first way to connect queries → collections → items, ensuring that seasonal or campaign-based products are surfaced at the right time and for the right searches.

What is it?

A new enhancement to the Collection Creation API allows customers to make items within a Collection discoverable for specific search phrases. This means that when a shopper searches for terms like “Sale,” “Holiday Deals,” or “Thanksgiving Sale,” the items from relevant seasonal or promotional collections (e.g., “Black Friday Collection”) can automatically appear in search results with no manual items association or merchandising rules required.

This feature gives merchants a lightweight, API-only way to directly associate search queries with entire collections of items, improving recall and discoverability while reducing manual merchandising overhead.

Note: This functionality is currently available only via the API, with dashboard and UI support coming soon.

Why this matters

Previously, there was no automatic link between seasonal or promotional collections and shopper queries:

• Items in those collections weren’t discoverable by campaign-related terms, since they often lacked explicit query associations or metadata.
• Merchants had to rely on manual rules to approximate this behavior, an inconsistent and time-consuming process, often without good item-level attribution for seasonal relevance.

With Discoverable Collections, Constructor bridges this gap, letting merchants efficiently map search phrases to collections so that the right items appear automatically when shoppers search for relevant terms.

How does it work?

A new optional parameter, discoverable, has been added to the Collection Creation API.
 When creating or updating a Collection, you can set discoverable: true and define phrases and match types similar to how redirects are configured.

Each discoverable configuration includes:

• match_type (string, default to PHRASE): The matching logic for the phrase.

  • "EXACT" – The pattern must exactly match the search query.
  • "UNORDERED" – All tokens in the pattern must match the query, but order doesn’t matter.
  • "PHRASE" – All tokens must match, but the query may include additional tokens.
• pattern (string, required): The phrase pattern that triggers item discovery.
  
  

By default, discoverable is false to preserve existing behavior.

Example Request

Below is a simple example of creating a discoverable Collection that associates its items with “sale” and “Thanksgiving sale” search queries:

curl -X POST https://ac.cnstrc.com/v1/collections \

  -H "Content-Type: application/json" \

  -H "Authorization: Bearer/Basic YOUR_API_TOKEN" \

  -d '{

    "display_name": "Black Friday Test Collection",

    "id": "bf25-cnstrc",

    "filter_expression": {

      "name": "group_id",

      "value": "all"

    },

    "discoverable": true,

    "matches": [

      {

        "pattern": "sale",

        "match_type": "PHRASE"

      },

      {

        "pattern": "Thanksgiving sale",

        "match_type": "PHRASE"

      }

    ]

  }'

In this example, items within the “Black Friday Test Collection” become discoverable whenever shoppers search for “sale” or “Thanksgiving sale.”

What problem does it solve?

The Discoverable Collections Items feature eliminates the need for complex rule management and inconsistent boosting strategies. By connecting queries → collections → items directly, merchants can:

• Automatically surface seasonal or campaign items for relevant search terms.
• Reduce manual merchandising effort while improving accuracy.
• Increase recall and relevance for high-intent seasonal queries.
  
  

Availability

The Discoverable Collections Items feature is available today via the Collection Creation API. Dashboard and UI support are coming soon to make discoverability even easier to configure.

Introducing a major update to API tokens that gives your engineering and admin teams precise, "least-privilege" control over API access.

The Challenge: The "All-or-Nothing" API Key

Previously, API tokens (now referred to as Legacy tokens) were company-wide, granting full read and write access to all Constructor endpoints across all your indexes. While powerful, this created potential risks. A leaked token technically, could expose all your data, and a simple misconfiguration in a script could accidentally apply changes to the wrong environment.

The Solution: API tokens with Custom Level of Access

Now, you can build API tokens with a specific, limited scope. When creating a new token, you can define:

• Indexes: Specify which indexes the token can access. This is perfect for isolating your Production, Staging, and Dev environments or managing different websites.
• Scopes: Select which API endpoints the token can use (e.g., searchandising.refined_queries, searchabilities,  synonyms).
• Permission: Define the permission level for those scopes: Read & Write, Read, or Write.
• Expiration Date: Set an optional expiration date. We recommend renewing API tokens regularly.

By limiting access to what is really needed, you reduce security risks if a token gets compromised and rule out the possibility of applying changes to the wrong environment.

Putting API Tokens into Practice

This new control allows you to securely manage complex, multi-team workflows:

• For Integration Scripts: Create an API token that has access only to scopes within the dev_index to test things before applying changes in production.
• For Regional Teams: Give your EU engineering team an API token that can Read & Write to all scopes only on the eu_site index, preventing accidental changes to the US site.

Better Together: API Tokens + Customizable User Roles

This update works hand-in-hand with our recent Customizable User Roles feature. Only users assigned with a role that has Manage API tokens permissions can set up API tokens. Users' ability to create API tokens is limited by their role permissions. An administrator can create tokens for any scope, but a user with a specific role (e.g., "US Merchandiser") can only create API tokens for the indexes and features they are already permitted to access. 

This ensures your permission model is consistent, from the dashboard UI right down to the API.

A Note on Legacy API Tokens

Your existing tokens (now labeled Legacy tokens in the dashboard) will continue to work without interruption. However, you can no longer create new tokens of this type. We highly recommend you audit your existing integrations and begin migrating to the new, more secure API tokens as part of your team's security best practices.

How to Get Started

This feature is now live for all customers. Administrators and users with the appropriate permissions can create new tokens by navigating to Integration > API Tokens in the dashboard.

For a complete, step-by-step guide, please visit our updated documentation: Generate and manage API tokens.

The dashboard analytics experience it taking a big leap forward. Starting today, all Constructor dashboard users can enjoy a more powerful, searchable, and segmentable analytics interface designed to make finding insights effortless.

With this update, merchandisers can:

• 🔎 Search within analytics tables across Search, Browse, and Recommendations — no more manual scrolling or exporting to find specific data points.
• ↕️ Sort by key metrics (clicks, conversions, revenue, etc.) to instantly spot what’s performing best — or what needs attention.
• 🌎 Filter analytics to uncover how different audiences behave: by geo, device type, customer-uploaded segments, Affinity, or RFM segments.

In short: you can now slice, search, and sort performance data however you need — directly in the dashboard.

Why it matters 🎯

Our users have long asked for better ways to prove impact and make data-backed decisions faster. This release brings analytics closer to that vision:

• Understand who your shoppers are and how they behave across Search, Browse and Recommendations.
• Quickly compare audience segments (e.g. iOS vs Android shoppers, Canada vs US, newcomers vs loyal shoppers).
• Focus on the moments that drive your business without leaving the dashboard or relying on exports.

These improvements make analytics both more powerful and more human, helping merchandisers move from data collection to real, actionable insight.

What’s next 🔜 

We’re continuing to expand these capabilities across the entire dashboard — bringing segment-level analytics, powerful tables, and unified interactions to more pages and reports soon.

Our mission is simple: to help merchandisers spend less time searching for insights, and more time acting on them.

We are excited to release a mighty enhancement to the Customizable User Roles feature: you can now assign multiple roles to a single user directly from the dashboard. This simplifies permission management and scaling your team's access with enterprise-grade flexibility.

The Challenge: Scaling Role Management

Since launching Customizable User Roles, we've heard feedback from large teams managing numerous brands, regions, or environments. A common challenge was managing users who needed combined permissions.

For example, to grant a developer access to both the EMEA and NA indexes, you had to create a specific "Dev EMEA + NA" role. For complex teams, this led to a long, hard-to-maintain list of "combination" roles (e.g., "Merchandiser US+EU", "Merchandiser B2B+B2C").

The Solution: Multiple Roles for Simple, Granular Control

With this update, you can now assign the existing "Dev EMEA" role and the "Dev NA" role to the same user. This approach provides powerful benefits:

• Reduce Admin Overhead: You don't need to create and manage dozens of redundant "combination" roles. Simply assign the building blocks you've already created.
• Scale with Flexibility: Easily manage permissions as your team grows and responsibilities change. Need to give a B2C merchandiser temporary access to the B2B site? Just add the "B2B Merchandiser" role and remove it when the project is done.
• Smart, Additive Permissions: Access is combined in the most permissive way. If one role grants View access and another grants Edit access for the same feature, the user will automatically get Edit access.

How to Get Started

Users with the Manage users permission can select and assign multiple roles to a single user directly from the dashboard. Navigate to the User Management page by clicking on your name in the bottom left corner, and then, Team Members. Click on the current role assigned to a user and select multiple roles in the dropdown.

If you have any questions or feedback on the update or the Constructor dashboard in general, please connect with your Customer Success Manager or contact us through support@constructor.io.

What's new

You can now target customer-defined user segments across most searchandising rules—not just Boost & Bury. That means you can adjust ranking, recall, content, and slotting for specific audiences (e.g., "US App Users", "Loyalty Tier Gold", "Clicked Meta Ad A") without rebuilding pages or bluntly applying rules to everyone.

You can now

• Apply segments to key rules and surfaces
  • Boost & Bury — Search, Browse, Campaigns, Recommendations, Global
  • Item Slotting (incl. CSV & faceted browse) — Search, Browse, Campaigns, Recommendations
  • Attribute-based Slotting — Search, Browse, Campaigns, Recommendations
  • Allowlist / Blocklist — Search, Browse, Campaigns, Recommendations (Blocklist also on Global)
  • Content Rules — Search, Browse, Campaigns
• Preview as a segment when creating Campaigns: Impersonate a selected segment to see exactly what that audience will experience before you ship.

Why it matters

Previously, segments were available for Boost & Bury only. Teams either ignored insights or applied broad rules to all shoppers, diluting performance. With segments available across your core rule types, you can:

• Tune the same PLP differently per audience (locale, device, lifecycle stage).
• Move faster from marketing signal to on-site personalisation without duplicating pages.
• Protect performance by narrowing rules to only the shoppers they're meant for.

Example workflows

• Campaign continuity: For users who clicked a specific ad or email, slot the exact products that match the message they saw, right on arrival.
• Locale nuance: Slot a colorway or size range for only a particular country/segment without touching other markets.
• Compliance fast-track: Blocklist prohibited items for a single region while keeping them live elsewhere.
• Channel-aware content: Show different banners/copy to app users vs web visitors on the same PLP.

Who benefits

• Merchandisers partnering with Marketing: align landing experiences to campaign promises.
• Region/brand owners: tailor assortment and messaging by locale without forking your catalog.
• Compliance & ops teams: react quickly to region-specific restrictions.

Coming soon

• AI-generated segments
• Segments in Content Rules (Global)
• Segments in Variation Slicing
• Impersonation for Search, Browse, and Global

What’s new

We’ve supercharged Collections so merchandisers can build, reuse, and refine PLPs with fewer clicks.

You can now

• Export item IDs to CSV from a Collection in one click—for analysis or to seed a new Collection.
• Add, edit, and remove item IDs inline in the Collections UI—no extra CSV wrangling required.
• Copy a Collection across indexes or within the same index—reuse successful setups with minor tweaks.

Why it matters

Previously, small changes took a big effort—exporting item IDs required workarounds, editing meant creating and re-uploading CSVs, and reusing a Collection often meant rebuilding from scratch.

Now you can:

• Move faster from idea to live PLP.
• Keep Collections fresh with quick, precise Item ID updates.
• Replicate proven merchandising strategies across storefronts without busywork.

Example workflows

• Re-launch a winning PLP in a new market: Copy the Collection to another index, adjust a few IDs inline, and publish.
• Clear handoff material: Provide item ID CSVs for cross-team reviews, ensuring everyone’s working from the same list.
• Tweak on the fly: Paste a handful of new item IDs straight from a spreadsheet and remove outdated ones in seconds.

Introducing Online LLM Burying Models—a new AI-powered enhancement that makes your search results cleaner, sharper, and more relevant in real time.

Our system now analyses each query as it happens, identifying and removing the least relevant results on the fly. Unlike the previous offline model, which could only filter precomputed query–item pairs, this new online model works on every search call, ensuring consistent precision across your entire catalog.

Benefits include:

• Higher precision: Irrelevant or misleading products are automatically detected and pushed down or removed.
• Smarter intent understanding: The model interprets the true meaning of each query to deliver more accurate matches.
• Improved search quality: Cleaner and more relevant results help users find what they need faster.

This update strengthens your search engine’s ability to interpret intent and deliver only the most meaningful results, helping shoppers find exactly what they’re looking for with confidence.

This enhancement is now available in AB test to all our customers.

To learn more, please contact your Customer Success Manager or support team.

We are excited to announce the general availability of Customizable User Roles with View/Edit permissions. This powerful new capability is now live in the Constructor dashboard for all customers. 

This feature allows enterprise e-commerce companies to provide every member of their team with tailored access, ensuring they have exactly the tools they need to excel—without compromising security or control.

The Challenge: Scaling Operations Securely

As an e-commerce business scales, more teams rely on a central platform for daily tasks. The Merchandising team fine-tunes results across the product discover journey, the Marketing team builds campaign-specific collections, and the Development team manages integrations and indexes. Each team has a unique focus, and providing one-size-fits-all access can create bottlenecks and introduce the risk of accidental changes to critical settings.

The Solution: Granular Control, Tailored for Your Business

Customizable User Roles solve this challenge by providing precise control over what each user can do. This functionality allows you to:

• Safeguard Critical Settings: Protect company-level information, such as API tokens and user management, by restricting access to only designated administrators. 
• Isolate Access by Index: Assign users to specific indexes, making it perfect for managing different regions, websites, or environments (e.g., Staging vs. Production) without overlap. 
• Assign Feature-Specific Permissions: Grant Edit permissions for individual features. Empower your merchandisers to manage Searchandising and Facets while restricting access to A/B Testing or Recommendations for designated roles. 
• Promote Data-Driven Decisions with View-Only Access: Create view-only roles for executives, analysts, and other stakeholders. This allows them to access valuable performance reports and analytics without the ability to make changes. 

Putting Roles into Practice 

With this level of control, you can create highly specific roles that map directly to your operational structure: 

• The Digital Merchandiser (B2B): Gets Edit access to Searchandising, Facets , Collections, A/B Testing, and Global Facet Configuration for the B2B website index, but has View access everywhere else. 
• The Marketing Specialist: Can only Edit the Collections feature to prepare for an upcoming email campaign. 
• The Regional Manager (EU): Has View access to global indexes but can only Edit merchandising rules for the eu_site index. 
• The Developer: Is given Edit access to the staging_index to test a new integration but has only View access to the production environment.

How to Get Started

This feature is now available in your dashboard. Administrators can begin creating and assigning roles today by clicking on their name in the bottom left corner, then Team Members, then switch to the User Roles tab. For a detailed walkthrough on creating roles and assigning permissions, please visit our documentation guide.

If you have any questions or feedback on the new feature or the Constructor dashboard in general, please connect with your Customer Success Manager or contact us through support@constructor.io.
