I’d like to work on this issue because it combines backend development, database querying, and performance optimization.

I have experience building API-driven applications and working with structured data, and I’d approach this with a focus on accurate search results and scalable queries.

My approach would be to:

• Design the search and filtering query structure.
• Implement full-text search using the project's existing database/search infrastructure.
• Add flexible filters and support for combined queries.
• Optimize indexes and queries for efficient retrieval.
• Add pagination and appropriate validation.
• Track useful search analytics without collecting unnecessary data.
• Add tests for search accuracy, filters, complex queries, and edge cases.

I’ll aim for a clean search API that remains performant as the credential dataset grows.
