Some environments have enough memory > available to keep the entire FST based term dict in memory. We should add a > TermDictionary implementation that encodes all needed information for each > term into the FST (custom fst.Output) and builds a FST from the entire term > not just the delta. -- This message was sent by Atlassian JIRA (v6.1.5#6160) --------------------------------------------------------------------- To unsubscribe, e-mail: dev-unsubscr...@lucene.apache.org For additional commands, e-mail: dev-h...@lucene.apache.org
