org.apache.lucene.search.IndexSearcher
| IndexSearcher | | public class IndexSearcher extends Searcher (Code) | | Implements search over a single IndexReader.
Applications usually need only call the inherited
IndexSearcher.search(Query) or
IndexSearcher.search(Query,Filter) methods. For performance reasons it is
recommended to open only one IndexSearcher and use it for all of your searches.
Note that you can only access Hits from an IndexSearcher as long as it is
not yet closed, otherwise an IOException will be thrown.

| Method Summary | |
| public void | close()
Note that the underlying IndexReader is not closed, if
IndexSearcher was constructed with IndexSearcher(IndexReader r). | | public Document | doc(int i)
| | public Document | doc(int i, FieldSelector fieldSelector)
| | public int | docFreq(Term term)
| | public Explanation | explain(Weight weight, int doc)
| | public IndexReader | getIndexReader()
Return the
IndexReader this searches. | | public int | maxDoc()
| | public Query | rewrite(Query original)
| | public TopDocs | search(Weight weight, Filter filter, int nDocs)
| | public TopFieldDocs | search(Weight weight, Filter filter, int nDocs, Sort sort)
| | public void | search(Weight weight, Filter filter, HitCollector results)
|
| IndexSearcher | | public IndexSearcher(IndexReader r)(Code) | | Creates a searcher searching the provided index.
|
| close | | public void close() throws IOException(Code) | | Note that the underlying IndexReader is not closed, if
IndexSearcher was constructed with IndexSearcher(IndexReader r).
If the IndexReader was supplied implicitly by specifying a directory, then
the IndexReader gets closed.
