# 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.

  - ### withRetrieve

    public boolean withRetrieve()
    Description copied from class: `ReadTask`
    Return true if, with search and 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 support parameters must override this method to return true.
    Overrides:
      `supportsParams` in class `PerfTask`
    Returns:
      true iff this task supports command line params.
