------------------------------------------------------------------
Attached our initial version of the working ANY operator support for edismax
([^EPMCSRCH-269.patch]) - this is a proof-of-concept version which might break
the other parsers. We have it also in a form of external jar with edismaxplus
parser plugin (in a form metioned by Alexey in the first post - which for
maintainability reasons requires introducing some extension points in the
edismax source).

> When we query
> (<term A> OR <term B> OR <term C> OR <term D>)
> and in case a document contains 2 or more of these terms: only the highest
> scoring term should contribute to the final relevancy score; possibly lower
> scoring terms should be discarded from the scoring algorithm.
> Ideally I'd like an operator like ANY:
> (<term A> ANY <term B> ANY <term C> ANY <term D>)
> that has the purpose: return documents, sorted by the score of the highest
> scoring term.
