Fix Incorrect Custom Fields in SharePoint Search Suggestions
Question details
SharePoint list search suggestions are displaying numbers or alternative column data instead of the expected item title.
- Product
- SharePoint Online
- Device & OS
- not provided
- Scenario
- Searching for items within a SharePoint List using the built-in search bar.
- Observed behavior
- The search suggestions dropdown shows a number or another column's value rather than the expected title, usually due to a custom column being renamed.
Ensure you have Site Administrator or List Owner permissions to view list settings, inspect column properties, and initiate search reindexing.
Verify the Internal Field Name of the Title Column
Check if a custom column was renamed instead of using the built-in Title field, which causes mapping issues in search suggestions.
SharePoint relies heavily on its built-in 'Title' field for search suggestions and item linking. If you created a new custom column and merely renamed it to 'Title', SharePoint will still reference the original internal field name (which might be a number or another string). This mismatch causes search suggestions to display the wrong data.
Navigate to your SharePoint list, click the gear icon in the top right corner, and select 'List settings'.
Scroll down to the 'Columns' section and click on the column you are using as your title.
Look at the URL in your browser's address bar. At the very end of the URL, find the 'Field=' parameter. If the value after 'Field=' is not exactly 'Title', it means this is a custom field.
If you discover you are using a renamed custom field, you will need to migrate your data to the actual built-in 'Title' field for search suggestions to map correctly automatically.
Review Search Schema and Reindex the List
Force SharePoint to re-crawl your list data to ensure recent column changes are reflected in search results.

Frequently Asked Questions
Why does SharePoint show a number instead of the title in search?
This usually happens when the default 'Title' column is hidden or replaced, and a new custom column was created and renamed to 'Title'. Because the new column's internal name is different (sometimes generated as a number or random string), SharePoint's search suggestions pull the wrong metadata.
Can I change the search suggestion mapping in SharePoint Online?
Direct modification of search suggestion mappings is highly limited in SharePoint Online because it lacks the Central Administration tool available in on-premises versions. The system automatically prioritizes the built-in Title field, so it is highly recommended to use it.
How long does it take for SharePoint search to update after reindexing?
In SharePoint Online, continuous crawls typically pick up changes within 15 to 30 minutes. However, depending on the server load and the size of your list, it can occasionally take several hours for search suggestions to update completely.
