Hi Francois, I understand that disabling of ReversedWildcardFilterFactory has improved the performance.
But I am puzzled over how the leading wild card search like *lock is working even though I have now disabled the ReversedWildcardFilterFactory and the indexes have been created without ReversedWildcardFilter ? How does reverse indexing work even after disabling ReversedWildcardFilterFactory? Can anyone explain me how this feature is working. -Shyam -----Original Message----- From: François Schiettecatte [mailto:fschietteca...@gmail.com] Sent: Wednesday, January 18, 2012 7:49 AM To: solr-user@lucene.apache.org Subject: Re: Question on Reverse Indexing Using ReversedWildcardFilterFactory will double the size of your dictionary (more or less), maybe the drop in performance that you are seeing is a result of that?
