Syntax
public class SearchTravRetVectorHighlightTask : SearchTravTaskRemarks
Note: This task reuses the reader if it is already open. Otherwise a reader is opened at start and closed at the end.
Takes optional multivalued, comma separated param string as:
size[<traversal size>],highlight[<int>],maxFrags[<int>],mergeContiguous[<boolean>],fields[name1;name2;...]- traversal sizeThe number of hits to traverse, otherwise all will be traversed.
- highlightThe number of the hits to highlight. Will always be less than or equal to traversal size. Default is
(i.e. hits.Length). - maxFragsThe maximum number of fragments to score by the highlighter.
- fragSizeThe length of fragments.
- fieldsThe fields to highlight. If not specified all fields will be highlighted (or at least attempted).
Example:
"SearchVecHlgtSameRdr" SearchTravRetVectorHighlight(size[10],highlight[10],maxFrags[3],fields[body]) > : 1000Fields must be stored and term vector offsets and positions in order must be true for this task to work.
Other side effects: counts additional 1 (record) for each traversed hit, and 1 more for each retrieved (non null) document and 1 for each fragment returned.
