issue with linked (lookup) columns.

When I search within a table, I’m having an issue with linked (lookup) columns.

If I search using the displayed text from the linked column, no results are returned. However, it appears the search is instead using the underlying ID value from the related table.

Example:

• I have a document_lines table with a column called Doc Header
• This column is linked to a headings table
• In the UI, it displays:
  "section1: Brakes & Lines"
• But in the database, this entry has an ID of 7

Issue:

• Searching for "section1:" → returns no results
• Searching for "7" → correctly returns all related entries

Question:
Is there a way to make the search work against the displayed text (e.g. "section1: Brakes & Lines") instead of the underlying ID?
