One more question, "100 millions of possible locations." looks large. But 500Kb is relatively small compared to Lucene's capability. And I believe the performance difference between Lucene and MySql, or others, are much obvious at 1GB~10GB level. I heard numbers like 10x faster. Is it possible to get numbers in that range? --=20 Chris Lu ------------ Lucene Search RAD on Any Database http://www.dbsight.net --------------------------------------------------------------------- To unsubscribe, e-mail: java-user-unsubscribe@lucene.apache.org For additional commands, e-mail: java-user-help@lucene.apache.org
