Okay so big thanks for the help with getting the hon_lucene_synonyms plugin working. That is a big load off to finally have a solution in place for all our multi-term synonyms. We did find that the information in Step 8 about the plugin showing "SynonymExpandingExtendedDismaxQParser" for QParser does not seem to be correct, we only ever get "ExtendedDismaxQParser" but the synonym expansion is definitely working.
In implementing it though, the one thing I'm still having an issue with is trying to figure out how I can get results on the original term to appear first in our results and matches on the synonyms lower in the results. The plugin includes settings for an originalboost and synonymboost, but that doesn't seem to be working along with all the other edismax boosts I'm doing. We search across a number of fields, each with their own boost and then do phrase searches with boosts as well. My params look like this: params["defType"] = 'synonym_edismax'; params["qf"] = 'body^0.5 productinfo^1.0 keywords^2.0 prodname^10.0 prodnumbertext^20.0'; params["pf"] = 'productinfo^1 body^5 keywords^10 prodname^50'; params["pf2"] = 'productinfo^1 body^5 keywords^10 prodname^50'; params["pf3"] = 'productinfo^1 body^5 keywords^10 prodname^50'; params["ps"] = 1; params["tie"] = 0.1; params["synonyms"] = true; params["synonyms.originalBoost"] = 2.0; params["synonyms.synonymBoost"] = 0.5; And here's an example of what the plugin gives me for a search on "sbc" which includes synonyms for "sb" and "small block".... I don't really know enough about this to figure out what exactly it's doing but since all of the results I am getting first are ones with "small block" in the name, and the ones with "sbc" in the prodname field which should be first are buried about 1000 documents in, I know the originalboost and synonymboost aren't working with all this other stuff. Ideas how to fix this? With the normal synonym filter we just set up copies of the fields that could have synonyms to use with that filter applied and had a lower boost on those. Not sure how to make it work with this custom query parser though. +((prodname:sbc^10.0 | body:sbc^0.5 | productinfo:sbc | keywords:sbc^2.0 | (((prodnumbertext:sbc prodnumbertext:small prodnumbertext:sb) prodnumbertext:block)~2)^20.0)~0.1^2.0 (((+(prodname:sb^10.0 | body:sb^0.5 | productinfo:sb | keywords:sb^2.0 | (((prodnumbertext:sb prodnumbertext:small prodnumbertext:sbc) prodnumbertext:block)~2)^20.0)~0.1 ()))^0.5) (((+(((prodname:small^10.0 | body:small^0.5 | productinfo:small | keywords:small^2.0 | prodnumbertext:small^20.0)~0.1 (prodname:block^10.0 | body:block^0.5 | productinfo:block | keywords:block^2.0 | prodnumbertext:block^20.0)~0.1)~2) (productinfo:"small block"~1 | body:"small block"~1^5.0 | keywords:"small block"~1^10.0 | prodname:"small block"~1^50.0)~0.1 (productinfo:"small block"~1 | body:"small block"~1^5.0 | keywords:"small block"~1^10.0 | prodname:"small block"~1^50.0)~0.1))^0.5)) () Mary Jo
