Is it possible to have synonyms for a term boosted (with a value lower than
An example would be a car-rental system, where you can specify the class of

I would like to be able to do one query that has a fallback that also
allows the term medium when you search for economic, but I want it boosted
with a certain value. So a standard synonym file wouldn't quite do the
I could of course have a query-time expansion of the synonyms with a SHOULD
boolean query and boost the individual terms I want to match, but that
would involve lots of complex query building. It would be super nice if I
could let ES handle this...
Does anyone have experience with build this kind of system with
ElasticSearch? Any thoughts on how else to implement it?
