Partial Supplier Name Search Not Working in Custom Supplier AI Agent

Summary:

I have configured REST APIs in a custom AI Agent to search suppliers based on user input such as Supplier Number and Supplier Name.

The search works as expected for Supplier Number, including range searches (for example, 2500 to 2505) and behaves similar to a LIKE operator in SQL.

However, the same behavior is not working for Supplier Name. The API returns results only when the full supplier name (for example, “ABC Corporation Inc”) is provided, but not when I search using a partial name such as “ABC”.

Could you please advise what might be missing or incorrectly configured in the API to enable partial or “starts with” searches for Supplier Name?
