Hi,
I have a question.
In my program, I need to check whether the input query is a MatchAll Query =
that contains no terms, or a Query (any variant) that has at least one term=
. For typical Term queries, this seems reasonable to be done with Query.ext=
ractTerms(Set<> terms) which gives the list of terms.=C2=A0
However, when there is a NumericRangeQuery, this method throws an Unsupport=
edOperationException.
How can I determine that a NumericRangeQuery or any non-Term query exists i=
n the Input Query and differentiate it from the MatchAllQuery?=C2=A0-- SRK
