Thanks Yonik and Maria. It make sense, if we reduce the number of terms, term enum becomes a very good solution. @Yonik : do we still check the prefix on the term dictionary one by one, or an FST is used to identify the set of candidate terms ?
I will check the code later, Regards ----- --------------- Alessandro Benedetti Search Consultant, R&D Software Engineer, Director Sease Ltd. - www.sease.io -- View this message in context: http://lucene.472066.n3.nabble.com/prefix-facet-performance-tp4330684p4331553.html Sent from the Solr - User mailing list archive at Nabble.com.
