Britta Weber 567a50c29b [function_score] apply min_score to sub query score if no function provided
For optimization pruposes a function score query with an empty function
will just result in the original sub query. However, sometimes one might
want to use function_score query to actually filter out docs within for example
bool clauses by using the min_score functionallity.
Therefore the sub query should only be used without wrapping inside
a function_score query if min_score was also not set.
