[Improvement]Performance Optimization for the `search` API

[earayu]

The current search API needs performance improvements and better logging/error handling for easier troubleshooting.

Right now, it appears to use the "retrieval test" logic, which unnecessarily saves a record to the database for every search query.

I suggest splitting it into two separate APIs:

1. A core search API: Focused on performance, without saving records to the database.
2. A retrieval_test API: Keeps the current behavior for testing purposes.

This change would significantly improve performance and make the API's purpose clearer.
