Faceted search engine with scoring -

Faceted search engine with scoring -

i'm looking search engine solution whereby there attributes each document can filtered against, not absolutely - scored.

doc1 has attributes a, b , c doc2 has attributes b , c

if user chooses attribute "a" only, won't remove doc2, it'll score doc1 higher...

are there search engines can that?

you can build solr. wouldn't utilize built-in facets; instead, expose attributes links (perhaps in facet-like way) , utilize them add together scoring weight attribute, can sent parameter in solr query on fly.
