Could multiple indexers change same collections at the same time?
Hi,
I remembered I tested earlier lucene 1.4 and 2.4, and found the following:
# it is OK for multiple searchers to search the same collection.
# it is OK for one IndexerWriter to edit and multiple searchers to search
at the same time.
# it is generally NOT OK for multiple IndexerWriter to change same collection
at the same time.
Could you confirm briefly if above are true and give me Yes/No answer whether
in latest lucene 3x above conclusions are still OK?
Thanks very much for helps, Lisheng

Yes, all of that still applies to Lucene 3x and 4x, and is unlikely to
change any time soon.
