Users need to resolve an issue where configured filters and content type columns fail to display in SharePoint's PnP Modern Search web parts.

Fixing Missing PnP Modern Search Filters and Results Columns in SharePoint

Product: Microsoft SharePoint
Device & OS: not provided
Scenario: Customizing the Search Filters and Search Results web parts using PnP Modern Search v4.
Observed behavior: Certain configured filters or content type columns are missing and do not appear in the search web parts despite being set up.

Before you start

Ensure you have Site Collection Administrator permissions and that a full search crawl or site re-index has been completed recently to apply any recent schema changes.

Solution 1Recommended

Verify Managed Properties and Web Part Configuration

Review the underlying SharePoint search schema and confirm that your custom columns are correctly mapped and configured in the web parts.

PnP Modern Search relies heavily on the SharePoint Search Schema. If a column is not mapped to a 'Refinable' managed property, it will not be available for filtering or displaying correctly in the search results.

Check Managed Properties

Go to Site Settings > Search Schema. Ensure that the crawled properties corresponding to your missing columns are mapped to Refinable Managed Properties (e.g., RefinableString00).

Review Filter Configuration

Edit the SharePoint page, select the PnP Search Filters web part, and open the property pane. Confirm that the exact Managed Property names are added to the filter settings.

Verify Search Results Display Settings

Open the property pane for the PnP Search Results web part. Navigate to the 'Selected properties' field and ensure your Managed Properties are checked so the data is retrieved.

Verify Managed Properties and Web Part Configuration

Re-indexing Required: After making any changes to the Search Schema, you must re-index the document library or site and wait for Microsoft 365 to complete the background crawl before changes take effect.

Consult the Microsoft Q&A Community

Since PnP Modern Search v4 is a community-driven customization component, specialized developer support is often required for complex configuration limitations.

Frequently Asked Questions

Why are my mapped crawled properties not showing up as Refinable strings?

After mapping a crawled property to a Refinable managed property in SharePoint, you must manually request a re-index of the list or site. The property will not appear in PnP Search until the background search crawl is completely finished.

Does PnP Modern Search v4 support all default SharePoint columns automatically?

No. While some default columns are ready to use, custom columns and certain built-in columns must be manually mapped to Managed Properties in the SharePoint Search Schema to be utilized as filters or result columns.

How can I check if the Search Results web part is actually retrieving my custom property?

You can use the 'Selected properties' field in the PnP Search Results web part configuration pane to ensure your specific managed property is being actively requested from the SharePoint search API.
