## org.apache.lucene.benchmark.byTask.tasks
Class SearchTravTask

    java.lang.Object
      org.apache.lucene.benchmark.byTask.tasks.PerfTask
          org.apache.lucene.benchmark.byTask.tasks.ReadTask
              org.apache.lucene.benchmark.byTask.tasks.SearchTravTask

All Implemented Interfaces:
  Cloneable

Direct Known Subclasses:
  SearchTravRetHighlightTask, SearchTravRetLoadFieldSelectorTask, SearchTravRetTask

    public class SearchTravTask

extends ReadTask

Search and Traverse task.

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 param: traversal size (otherwise all results are traversed).

Other side effects: counts additional 1 (record) for each traversed hit.

Constructor Detail

### SearchTravTask

    public SearchTravTask(PerfRunData runData)

Method Detail

### withRetrieve

    public boolean withRetrieve()

  Description copied from class: `ReadTask`
  Return true if, with search & results traversing, docs should be retrieved.

  Specified by:
    `withRetrieve` in class `ReadTask`

### withSearch

    public boolean withSearch()

  Description copied from class: `ReadTask`
  Return true if search should be performed.

  Specified by:
    `withSearch` in class `ReadTask`

### withTraverse

    public boolean withTraverse()

  Description copied from class: `ReadTask`
  Return true if, with search, results should be traversed.

  Specified by:
    `withTraverse` in class `ReadTask`

### withWarm

    public boolean withWarm()

  Description copied from class: `ReadTask`
  Return true if warming should be performed.

  Specified by:
    `withWarm` in class `ReadTask`

### getQueryMaker

    public QueryMaker getQueryMaker()

  Description copied from class: `ReadTask`
  Return query maker used for this task.

  Specified by:
    `getQueryMaker` in class `ReadTask`

### traversalSize

    public int traversalSize()

  Description copied from class: `ReadTask`
  Specify the number of hits to traverse. Tasks should override this if they want to restrict the number of hits that are traversed when `ReadTask.withTraverse()` is true. Must be greater than 0.

  Read task calculates the traversal as: Math.min(hits.length(), traversalSize())

  Overrides:
    `traversalSize` in class `ReadTask`
  Returns:
    Integer.MAX_VALUE

### setParams

    public void setParams(String params)

  Description copied from class: `PerfTask`
  Set the params of this task.

  Overrides:
    `setParams` in class `PerfTask`

### supportsParams

    public boolean supportsParams()

  Description copied from class: `PerfTask`
  Sub classes that supports parameters must overide this method to return true.

  Overrides:
    `supportsParams` in class `PerfTask`
  Returns:
    true iff this task supports command line params.
