Hi Otis, Since I have expand="true" in SynonymFilterFactory, the DebugQuery shows the query is expanded with all the synonyms. Eg; Without synonym the query is: Review:amaz | name:amaz | description:amaz
With Synonym the query is: (Review:amaz Review:fabul Review:improbable Review:incredible )| name:amaz | (description:amaz description:fabul description:improbable description:incredible ) There are around 20 synonyms for each word. I am not sure if 20 keywords are causing the latency.

I will verify the debugQuery and update you with the results Thanks, Kalyan Manepalli -----Original Message----- From: Otis Gospodnetic [mailto:[EMAIL PROTECTED] Sent: Tuesday, November 11, 2008 11:26 AM To: solr-user@lucene.apache.org Subject: Re: Synonyms impacting the performance Hi, That doesn't sound normal, no. Do you know what your query looks like after synonym expansion? (you can use debugQuery=true or peek at the logs) Is that really the only thing that changed? In other words, if you comment out the SynonymFactory in solrconfig.xml and restart Solr do things really go back to 125ms? Are you seeing slowness for one particular query or for all of them?

The synonyms file is counts around 1000 words. The average querytime without synonyms is around 125 ms and with synonyms it jumps to 20 secs. Am I missing something here, since this doesn't look like a normal behavior Any suggestions on this will be helpful Thanks, Kalyan Manepalli
