Strange results when combining German2 snowball with ngram and highlighting matches.

[bogn]

When using the combo analyzer with the sub analyzers German2 snowball and ngram I get wrong highlights at positions where the queried word didn't occur in the input text. See gist 5411318. Changing order of the sub_analyzers doesn't change anything. default_index and default_search are different because ngram shouldn't be used for search analysis. I don't have that much experience in the field of full-text search but not using combo analyzer and using a fillter array

[ "ngram_filter", "germansnow" ]

where appropriate yields correct results for me. But as far as I understand it now is not the same as using the combo analyzer.

As far as my requirements go, I started here: http://jprante.github.io/lessons/2012/05/16/multilingual-analysis-for-title-search.html because we have multilingual titles as well.
