Class SearchTravRetHighlightTask
java.lang.Object
org.apache.lucene.benchmark.byTask.tasks.PerfTask
org.apache.lucene.benchmark.byTask.tasks.ReadTask
org.apache.lucene.benchmark.byTask.tasks.SearchTravTask
org.apache.lucene.benchmark.byTask.tasks.SearchTravRetHighlightTask
- All Implemented Interfaces:
Cloneable
Search and Traverse and Retrieve docs task. Highlight the fields in the retrieved documents.
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: type[<enum>],maxFrags[<int>],fields[name1;name2;...]
- type - the highlighter implementation, e.g. "UH"
- maxFrags - The maximum number of fragments to score by the highlighter
- fields - The fields to highlight. If not specified all fields will be highlighted (or at least attempted)
"SearchHlgtSameRdr" SearchTravRetHighlight(type[UH],maxFrags[3],fields[body]) > : 1000Documents must be stored in order for this task to work. Additionally, term vector positions can be used as well, and offsets in postings is another option.
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.

setup
Description copied from class:PerfTaskTask setup work that should not be measured for that specific task. By default it does nothing, but tasks can implement this, moving work fromPerfTask.doLogic()to this method. Only the work done inPerfTask.doLogic()is measured for this task. Notice that higher level (sequence) tasks containing this task would then measure larger time than the sum of their contained tasks. -
