getFilter

public Filter getFilter(Filter fastMatchFilter,
               ValueSource valueSource)

Description copied from class: Range

Returns a new Filter accepting only documents in this range. This filter is not general-purpose; you should either use it with DrillSideways by adding it to DrillDownQuery.add(java.lang.String, java.lang.String...), or pass it to FilteredQuery using its FilteredQuery.QUERY_FIRST_FILTER_STRATEGY. If the ValueSource is static, e.g. an indexed numeric field, then it may be more efficient to use NumericRangeFilter. The provided fastMatchFilter, if non-null, will first be consulted, and only if that is set for each document will the range then be checked.
