public void search(Query query, HitCollector results) throws IOException
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 void setSimilarity(Similarity similarity)
Similarity.setDefault(Similarity)
public Similarity getSimilarity()
This defaults to the current value of Similarity.getDefault()
.
