Index-time synonym expansion maximizes recall (not missing any documents,
especially partial matches), but minimizes precision and relevancy - you
are unable to select or boost exact matches. Ditto for ngrams.
As Erik indicates, using edismax with separate fields for precision (exact
matches) and
One technique that works well is to use copyField to end up with two indexed
fields, one with synonyms, one without. Then you can qf=title^5
title_with_synonyms^1 with edismax and weight the “exacter” field higher than
one with synonyms.
