Koha Library System Debugging

I'm experiencing a few bugs in my Koha library system that need resolving. The issues are primarily occurring in the cataloging and merging areas.

- Cataloging: The search functionality within the cataloging system is not working correctly and is providing inaccurate results.

- Merging: There are also issues with the merging functionality.

I need a professional who can thoroughly debug the system and fix these issues. Experience with Koha is essential. Skills in library system management and debugging software are highly desirable. Please only apply if you can provide a quick turnaround time for these fixes.
