As with all searches start simple and see if you find what you are looking for.

The library search scans: Categories, Groups, Document Titles, and Descriptions. It provides a weighted result based on the matches if finds with your query string.

Usually the best thing is to enter the most unique portion of a document title. For example if the documents have a number or distinctive name: just enter the single word.

Refine your search to include more words only if you get too many results.
