distanceSubQueryNotAllowed
public String distanceSubQueryNotAllowed()
Description copied from interface:DistanceSubQueryWhen distanceSubQueryNotAllowed() returns non null, the reason why the subquery is not allowed as a distance subquery is returned.
When distanceSubQueryNotAllowed() returns null addSpanNearQueries() can be used in the creation of the span near clause for the subquery.- Specified by:
