public Similarity getSimilarity()

Expert: Return the Similarity implementation used by this Searcher.

This defaults to the current value of Similarity.getDefault().

public final Hits search(Query query)
            throws IOException

Returns the documents matching query.

public Hits search(Query query,
                   Filter filter)
            throws IOException

Returns the documents matching query and filter.

public Hits search(Query query,
                   Filter filter,
                   Sort sort)
            throws IOException

public void search(Query query,
                   HitCollector results)
            throws IOException

Lower-level search API.

HitCollector.collect(int,float) is called for every non-zero scoring document.

Applications should only use this if they need all of the matching documents. The high-level search API (search(Query)) is usually more efficient, as it skips non-high-scoring hits.

Note: The score passed to this method is a raw score. In other words, the score will not necessarily be a float whose value is between 0 and 1.

public Hits search(Query query,
                   Sort sort)
            throws IOException

Returns documents matching query sorted by sort.

public void setSimilarity(Similarity similarity)

Expert: Set the Similarity implementation used by this Searcher.
