docs: fix broken SearchCriteria reference link (#77)

The FILTER-SEARCH-RESULTS.md file referenced a non-existent
SEARCH-CRITERIA.md document. The SearchCriteria documentation
exists in LIBRARY-API.md with comprehensive coverage of
construction, builder methods, fields, and examples.

Updated the link to point to the correct section anchor.
