Hello all,
I had a look to the new release of Lucene (2.9) [1].
There is quite a number of changes (bug fixes, new features) with lots
of new methods which will be the one to use in 3.0.
Migrating GeoNetwork to this release is quite easy and doing some
Yourkit tests make searches a little little faster.
Using this release, we can see that we're using now lots of deprecated
methods and a migration to lucene 3.0 will require much more works
than migrating to 2.9.
Do you think we should make an update for 2.5 ?
Ciao.

hi Francois,
if it’s not too much work I’d say Yes ! Seeing that 2.5 by definition will be an “unstable” GN release we can take some chances 
And let’s then keep an eye out on Lucene bugfix releases that often arrive soon after a major release, seeing also the email discussion on Lucene’s list where for some people, 2.9 was much slower than 2.4.1, and I’m not sure this was completely resolved [1].
