Subject RE: Lucene 2.9 status (to port to Lucene.Net)
Date Thu, 16 Apr 2009 15:57:00 GMT
These issues all depend so much on each other, i would suggest to simply try
Lucene-2.9-dev trunk (e.g. from downloaded from Hudson). We have this
running here without any problems. The problem with unreleased Lucene is
more, that if you try new features, there may be non-compatible changes
until the release, so you must keep track on changes on the components you
try out.
In general: If everything works for you, and you have backups of your
indexes, you can simply try out. If it works correctly, just use it!
Patching the relased version may make it more unstable than using the
development tree, that is more tested by all our committers :)
