Wrong result in more_like_this query

Hi,

i've tried the "more like this" elastic search query and wondered why i am
getting a wrong result. Maybe i misunderstand the elastic search "more like
this" query... ?
Can anybody explain how to use it?

I've watched to the following JUnit test and was a little bit confused #?

github.com

elastic/elasticsearch/blob/0.19/src/test/java/org/elasticsearch/test/integration/mlt/MoreLikeThisActionTests.java

In the rows 88 and 120 are two expected hits 11 and 11. Why ?
Is the Junit test wrong?

What do the min_term_freq and min_doc_freq mean?
