- All Implemented Interfaces:
OffsetsRetrievalStrategy
public final class OffsetsFromPositions extends Object implements OffsetsRetrievalStrategy
This strategy applies to fields with stored positions but no offsets. We re-analyze the field's value to find out offsets of match positions.Note that this may fail if index data (positions stored in the index) is out of sync with the field values or the analyzer. This strategy assumes it'll never happen.
