But remember many Lucene apps won't see these speedups since I've : carefully minimized cost of tokenization and cost of document retrieval. I : think for many Lucene apps these are a sizable part of time spend indexing. true, but as long as the changes you are making has no impact on the tokenization/docbuilding times, that shouldn't be a factor -- that should be consiered a "cosntant time" adjunct to the code you are varying ... people with expensive analysis may not see any significant increases, but that's their own problem -- people concerned about performance will already have that as fast as they can get it, and now the internals of document adding will get faster as well. -Hoss --------------------------------------------------------------------- To unsubscribe, e-mail: java-dev-unsubscribe@lucene.apache.org For additional commands, e-mail: java-dev-help@lucene.apache.org
