queries
- Sub queries to match.minimumNumberMatch
- Per-document long value that records how many queries
should match. Values that are less than 1 are treated
like 1: only documents that have at least one
matching clause will be considered matches. Documents
that do not have a value for minimumNumberMatch
do not match.public java.lang.String toString(java.lang.String field)

works properly.
Typically a query will be equal to another only if it's an instance of
the same class and its document-filtering properties are identical that other
instance. Utility methods are provided for certain repetitive code.equals
