RE: Synonym Filter disable at query time
Just a heads up on a solution. copyField wasn't need, but a new fieldType and a non-indexed, non-stored field was added. Within a new Synonym processor that executes right before the AnalyzerQueryNodeProcessor, I was able to modify the field name for each node to point at the new field. Therefore I could build out the necessary synonym values from the tokenizer and then reassign them all back to the original field with whatever boosts they needed. This allowed me to retain the original value match, to keep it's boost at 1 and then boost the synonyms according to a user specified boost value. Works perfectly. Thanks again for the help. -- View this message in context: http://lucene.472066.n3.nabble.com/Synonym-Filter-disable-at-query-time-tp2919876p2923775.html Sent from the Solr - User mailing list archive at Nabble.com.

RE: Synonym Filter disable at query time
Just make another field using copyfield which the other field does not apply synonyms to the text and then search either the one with or without from the front end... that will be your selector. :) -Original Message- From: mtraynham [mailto:mtrayn...@digitalsmiths.com] Sent: Monday, May 09, 2011 11:17 AM To: solr-user@lucene.apache.org Subject: Synonym Filter disable at query time I would like to be able to disable the synonym filter during runtime based on a query parameter, say 'synoynms=true' or 'synonyms=false'. Is there a way within the AnaylzerQueryNodeProcessor or QParser that I can remove the SynonymFilter from the AnalyzerAttributes? It seems that the Analyzer has a hashmap for it's 'analyzers' but I cannot find the declaration of this item.

RE: Synonym Filter disable at query time
Awesome thanks! Also, you wouldn't happen to have any insight on boosting synonyms lower than the original query after they were stemmed, would you? Say if I had synonyms turned on: The TokenStream is setup to do Synonyms - StopFilter - LowerCaseFilter - SnowballPorter. Say I search for Thomas, synonyms produces Thomas, Tom, Tommy. The SnowballPorter produces Tom, Tommi, Thoma. Is there a way to know Thoma would match the original term, so it could be boosted higher? -- View this message in context: http://lucene.472066.n3.nabble.com/Synonym-Filter-disable-at-query-time-tp2919876p2920342.html Sent from the Solr - User mailing list archive at Nabble.com.
RE: Synonym Filter disable at query time
Actually now that I think about it, with copy fields I can just single out the Synonym reader and boost from an earlier processor. Thanks again though, that solved a lot of headache! -- View this message in context: http://lucene.472066.n3.nabble.com/Synonym-Filter-disable-at-query-time-tp2919876p2920510.html Sent from the Solr - User mailing list archive at Nabble.com.
RE: Synonym Filter disable at query time
I was thinking search both and boost non-synonym field perhaps? -Original Message- From: mtraynham [mailto:mtrayn...@digitalsmiths.com] Sent: Monday, May 09, 2011 1:20 PM To: solr-user@lucene.apache.org Subject: RE: Synonym Filter disable at query time Awesome thanks!
