CommonGramsQueryFilter

class CommonGramsQueryFilter(input: CommonGramsFilter) : TokenFilter

Wrap a CommonGramsFilter optimizing phrase queries by only returning single words when they are not a member of a bigram.

Example:

query input to CommonGramsFilter: "the rain in spain falls mainly"
output of CommomGramsFilter/input to CommonGramsQueryFilter: |"the, "the-rain"|"rain" "rain-in"|"in, "in-spain"|"spain"|"falls"|"mainly"
output of CommonGramsQueryFilter:"the-rain", "rain-in" ,"in-spain", "falls", "mainly"
