- All Implemented Interfaces:
QueryNodeProcessor
public class PointRangeQueryNodeProcessor extends QueryNodeProcessorImpl
This processor is used to convertTermRangeQueryNode
s toPointRangeQueryNode
s. It looks forStandardQueryConfigHandler.ConfigurationKeys.POINTS_CONFIG
set in theFieldConfig
of everyTermRangeQueryNode
found. IfStandardQueryConfigHandler.ConfigurationKeys.POINTS_CONFIG
is found, it considers thatTermRangeQueryNode
to be a numeric range query and convert it toPointRangeQueryNode
.
