QueryNodeProcessor
public class PointRangeQueryNodeProcessor extends QueryNodeProcessorImpl
This processor is used to convertTermRangeQueryNodes toPointRangeQueryNodes. It looks forStandardQueryConfigHandler.ConfigurationKeys.POINTS_CONFIGset in theFieldConfigof everyTermRangeQueryNodefound. IfStandardQueryConfigHandler.ConfigurationKeys.POINTS_CONFIGis found, it considers thatTermRangeQueryNodeto be a numeric range query and convert it toPointRangeQueryNode.
