Results from all facets highlighted in search results #429

1. Perform this search: https://www.documentcloud.org/search/Text:%20facility%20Group:%20nytimes%20Title:%20%22FISA%22
2. Scroll down to the document "Large Content FISA Order Documents"
3. Expand all search matches by clicking "Show all [n] pages"

Expected: Only the term "facility" should be highlighted in the results, since those results represent the document text, and the only thing we searched for in the text was "facility".

Actual: ❌ Values of all three search facets (text/group/title) are highlighted ("facility"/"nytimes"/"FISA", respectively).
