I have a field in my index which is using hyphenation decompounder for german.

When I index a document with the value "Anfrage-7078437-991506 (1).P93" this leads to the tokens "Anfrage", "frage", "7078437", "991506", "1" and "P93".

A search with MatchQuery for "Preisanfrage" and the operator AND has this document as result.  
"Preisanfrage" leads to the tokens "Preisanfrage" and "frage".

My question is: Why isn't AND used and only a document with "Preisanfrage" and "frage" is returned?  
Or is there something I can do to get this result.

So, the reason for this is, that a single input term `Preisanfrage` generates more than one output term `Preisanfrage & frage` and those will be combined with an or (as it would be confusing if an additional generated term during analysis would lead to a document not being returned at all, despite being an exact match for the term that was typed in).

The operator `AND` refers to the case when two input terms are send in the search request like `spam eggs` - then this will become a `spam AND eggs` query, regardless to what a single term expands to after analysis.

Hope that helps to understand. the issue.
