I'm always a little skeptical of general purpose search solutions. The hard part about search is ranking and relevance. BM25 and ANN similarity are great algorithms for sourcing documents, but without a ranking step the user is left to scroll through a lot of potentially relevant results that aren't sorted very well.

Searchbase also supports user-defined ranking; the user can provide keyword, geo-distance, and number “ranking modifiers” each with their own “weight”. (Similar to elasticsearch’s “RANK” filters).
