It seems advantageous to just make it really cheap to get a new view of the index (if you do it for every search, t amounts to the same thing, right?) Quite a bit of code in Lucene assumes a static view of the Index I think (even IndexSearcher), and it's nice to have a stable index view for the duration of a single request. > Similar to InstantiatedIndexReader, > it will be in sync with an index writer. Right... that's why I was clarifying. You can still make stable views of the index with multiple InstantiatedIndex instances, but it doesn't seem as efficient. -Yonik --------------------------------------------------------------------- To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
