Subject [Lucene.Net] [jira] [Updated] (LUCENENET-179) SnowballFilter speed improvment
Date Tue, 24 Jan 2012 05:51:40 GMT


Christopher Currens updated LUCENENET-179:

    Fix Version/s: Lucene.Net 3.0.3

I haven't looked at the code, but I'm adding it into 3.0.3 anyway.  When someone has the time
to look over it and test it, we can decide if we plan on including it or not.  At first glance,
it looks good, but I wouldn't want to sign off on it until we're sure it fits in with the
changes of 3.0.3 and passes all tests.

> I'm using Lucene.Net along with snowball stemming to index text from a database. The
class Lucene.Net.Analysis.Snowball.SnowballFilter uses the reflection API and the invoke method
to call the stem methods of snowball. I have written a Snowball filter which creates a delegate
and uses this delegate to stem the words afterwards. This approach improves the indexing speed
of my indexing program by about 10%. I would be happy if you include this code into
