Description

The GermanAnalyzer doesn't split compound nouns.

Doing this requires some auxiliary data files with strange licenses. But uschindler has documented and packaged everything up to make this easy: https://github.com/uschindler/german-decompounder

We added a Lucene API example (using CustomAnalyzer) to the README: https://github.com/uschindler/german-decompounder/pull/6

So I think it would be nice to link to this from the javadocs, it makes it really easy to download the datafiles and configure an appropriate analyzer, if you are OK with Latex and LGPL licenses for the data files (which many folks might be).
