words n-gram analyser

Does Solr 4.2 have n-gram filter over words, not symbols like
EdgeNGramFilterFactory.

I hoped NGramTokenFilterFactory serves this purposes but looks like it also
creates n-grams over symbols.

I used it this way 
<filter class="solr.NGramTokenFilterFactory" minGramSize="3"
maxGramSize="10"/>
in hope that I will get 3-words to 10-words

I think that ShingleFilterFactory is what you're looking for, see:

Best,
