public class SearchTravRetVectorHighlightTask
Search and Traverse and Retrieve docs task. Highlight the fields in the retrieved documents by using FastVectorHighlighter.
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;...]
"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.
