Contextual Synonym Filter

I need to create a contextual Synonym Filter:

I need that the Synonym Filter load different synonym configuration based on the fq query parameter.

I've already modified the SynonymGraphFilterFactory to load from DB (this is another requirement) but I can't understand how to make the fq parameter arrive to the Factory.

Maybe I need a Query Parser plugin?

Please help

Hi Luca,

I wonder if payloads might be able to solve your case for contextual
synonyms?

Hi Luca,
I believe this is not an easy task to do passing through Solr/Lucene 
internals; did you try to use what Solr offers out of the box?
For example, you could define several fields associated where each 
corresponding field type uses a different synonym set. So you would have

  * F1 -> FT1 -> SYNSET1
  * F2 -> FT2 -> SYNSET2
  * ...

if you query using *fq=F1:something* then the *FT1* (and the *SYNSET1*) 
will be used, if you query using *fq=F2:something* then the *FT2* (and 
the *SYNSET2*) will be used, and so on

I don't know your context so my suggestion could be absolutely in the 
wrong path

Best,
Andrea
