Flexible book search function

As a librarian, I would like to be able to search for books by their categories, title keywords and authors so that I can quickly locate a specific category or a specific book so that I can better manage the classification of books and recommend books to patrons.

• Administrator is able to select book category in the search field.
• Administrator can enter book title keywords and author name to search.
• The system displays a list of all books that meet the search criteria.
• The search results include title, author and availability status.
