# Concepts, subject, and another field

## Expectations:

* User searches for concept or subject along with {concept/subject} {contributor} {keywords} {format} {genre} {date} {fuzzy date} to refine this search
* Users expect works with exact match for reference number and matches for other information to appear first in results.
* Works that mention the reference number in other fields should follow the exact match in the search results

## Examples:

* Botany, 16th Century
* Hong kong 1870
* skull engraving
* women + medical schools
* Recipe books + England (may expect UK as well)
* Drugs 1960s
* PP/CRI DNA sketch
