Method Detail

• create

  public static ScoredDocIdCollector create​(int maxDoc,
                                            boolean enableScoring)

  Creates a new ScoredDocIdCollector with the given parameters.

  Parameters:

  maxDoc - the number of documents that are expected to be collected. Note that if more documents are collected, unexpected exceptions may be thrown. Usually you should pass IndexReader.maxDoc() of the same IndexReader with which the search is executed.

  enableScoring - if scoring is enabled, a score will be computed for every matching document, which might be expensive. Therefore if you do not require scoring, it is better to set it to false.

• getDefaultScore

  public abstract float getDefaultScore()

  Returns the default score used when scoring is disabled.

• setDefaultScore

  public abstract void setDefaultScore​(float defaultScore)

  Set the default score. Only applicable if scoring is disabled.

• scoredDocIdsIterator

  public abstract ScoredDocIDsIterator scoredDocIdsIterator()
                                                     throws IOException

  Throws:

  IOException

• getScoredDocIDs

  public ScoredDocIDs getScoredDocIDs()

• setNextReader

  public void setNextReader​(IndexReader reader,
                            int base)
                     throws IOException

  Description copied from class: Collector
  Called before collecting from each IndexReader. All doc ids in Collector.collect(int) will correspond to reader. Add docBase to the current IndexReaders internal document id to re-base ids in Collector.collect(int).

  Specified by:

  setNextReader in class Collector

  Parameters:

  reader - next IndexReader

  Throws:

  IOException
