Hi Ragnar,

thanks for your interest.

My plugin does not work well with Swedish. The german and swedish  
languages are close, but correct baseform reduction trees are required.  
For creating dictionary tree files, a training tool must be written or  
the original one must be used. If you are familiar with the GUI based  
Leipzig tools at  
[http://wortschatz.uni-leipzig.de/~cbiemann/software/toolbox/](http://wortschatz.uni-leipzig.de/~cbiemann/software/toolbox/) , you could  
try and find out how to build swedish compund tree dictionary files. You  
need a list of all swedish compound words.

Similar to compound word analysis is hyphenation based analysis. Watch  
out if there are hyphenation analysis routines for ES or Lucene. There is

[http://lucene.apache.org/core/4\_2\_0/analyzers-common/org/apache/lucene/analysis/compound/HyphenationCompoundWordTokenFilterFactory.html](http://lucene.apache.org/core/4_2_0/analyzers-common/org/apache/lucene/analysis/compound/HyphenationCompoundWordTokenFilterFactory.html)

and it is exposed by ES via

[https://github.com/elasticsearch/elasticsearch/blob/master/src/main/java/org/elasticsearch/index/analysis/compound/HyphenationCompoundWordTokenFilterFactory.java](https://github.com/elasticsearch/elasticsearch/blob/master/src/main/java/org/elasticsearch/index/analysis/compound/HyphenationCompoundWordTokenFilterFactory.java)
