Filtered Similarity Search

The Similarity Search function considers the entire database when searching for potential matches.

Please add support to specify a filter that will allow us to say "find similar accessions to this XYZ accession, but search only within { institute: { code: [ "NGA039" ] }, crop: [ "cassava" ] }"

This feature will be useful for Embedded Genesys where we need to limit this search to only the records of one institute.

The implementation needs to be generic.
