Search Functionality

Implement a search feature that allows users to search for specific values in the responses table. When a user clicks the search button or presses enter, the app should search the database for the value entered. Create a search button that triggers this functionality.

Start by locating the responses table handling and the database entry point used by the backend. Trace how the search button or Enter key can reach that flow, then verify that entering a value returns matching responses and that the search button triggers the same behavior.
