Add rate limiting for search

**Problem**
When working with components, the error messages could be more descriptive.

**Suggestion**
Improve error handling and add detailed error messages.

**Context**
This would help with debugging and maintenance.

The title requests rate limiting for search, while the body describes more detailed component error messages. First clarify which scope is intended, then locate the search entry point and existing error-handling path. Done means the agreed search requests are rate-limited and the relevant behavior is covered by the repository's existing checks.
