Method Detail |
public void search(Query query, Filter filter, HitCollector results) throws IOException
Searchable
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 (Searcher.search(Query)
) is usually more efficient, as it skips
non-high-scoring hits.
search
in interface Searchable
query
- to match documentsfilter
- if non-null, a bitset used to eliminate some documentsresults
- to receive hits

public int docFreq(Term term) throws IOException
Searchable
term

Called by search code to compute term weights.

IndexReader.maxDoc().
public TopDocs search(Query query, Filter filter, int n) throws IOException
Searchable
n

if non-null.
Called by Hits
.
Applications should usually call Searcher.search(Query)
or
Searcher.search(Query,Filter)
instead.

public Explanation explain(Query query, int doc) throws IOException
Searchable

.
This is intended to be used in developing Similarity implementations, and, for good performance, should not be displayed with every hit. Computing an explanation is as expensive as executing the query over the entire index.
