Constructor Detail

### RemoteSearchable

    public RemoteSearchable(Searchable local)
                     throws RemoteException

  Deprecated.
  Constructs and exports a remote searcher.

  Throws:
    `RemoteException`

Method Detail

### search

    public void search(Weight weight,
                       Filter filter,
                       Collector results)
                throws IOException

  Deprecated.
  Description copied from interface: `Searchable`
  Lower-level search API.

  `Collector.collect(int)` is called for every document.
  Collector-based access to remote indexes is discouraged.

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

  Specified by:
    `search` in interface `Searchable`
  Parameters:
    `weight` - to match documents
    `filter` - if non-null, used to permit documents to be collected.
    `results` - to receive hits
  Throws:
    `IOException`

### close

    public void close()
               throws IOException

  Deprecated.
  Description copied from interface: `Searchable`
  Frees resources associated with this Searcher. Be careful not to call this method while you are still using objects that reference this Searchable.

  Specified by:
    `close` in interface `Closeable`
  Specified by:
    `close` in interface `Searchable`
  Throws:
    `IOException`

### docFreq

    public int docFreq(Term term)
                throws IOException

  Deprecated.
  Description copied from interface: `Searchable`
  Expert: Returns the number of documents containing `term`.

  Specified by:
    `docFreq` in interface `Searchable`
  Throws:
    `IOException`
  See Also:
    `IndexReader.docFreq(Term)`

### docFreqs

    public int[] docFreqs(Term[] terms)
                   throws IOException

  Deprecated.
  Description copied from interface: `Searchable`
  Expert: For each term in the terms array, calculates the number of documents containing `term`. Returns an array with these document frequencies. Used to minimize number of remote calls.

  Specified by:
    `docFreqs` in interface `Searchable`
  Throws:
    `IOException`

### maxDoc

    public int maxDoc()
               throws IOException

  Deprecated.
  Description copied from interface: `Searchable`
  Expert: Returns one greater than the largest possible document number.

  Specified by:
    `maxDoc` in interface `Searchable`
  Throws:
    `IOException`
  See Also:
    `IndexReader.maxDoc()`

### search

    public TopDocs search(Weight weight,
                          Filter filter,
                          int n)
                   throws IOException

  Deprecated.
  Description copied from interface: `Searchable`
  Expert: Low-level search implementation. Finds the top `n` hits for `query`, applying `filter` if non-null.

  Applications should usually call `Searcher.search(Query,int)` or `Searcher.search(Query,Filter,int)` instead.

  Specified by:
    `search` in interface `Searchable`
  Throws:
    `IOException`

### search

    public TopFieldDocs search(Weight weight,
                               Filter filter,
                               int n,
                               Sort sort)
                        throws IOException

  Deprecated.
  Description copied from interface: `Searchable`
  Expert: Low-level search implementation with arbitrary sorting. Finds the top `n` hits for `query`, applying `filter` if non-null, and sorting the hits by the criteria in `sort`.

  Applications should usually call `Searcher.search(Query,Filter,int,Sort)` instead.

  Specified by:
    `search` in interface `Searchable`
  Throws:
    `IOException`

### doc

    public Document doc(int i)
                 throws CorruptIndexException,
                        IOException

  Deprecated.
  Description copied from interface: `Searchable`
  Returns the stored fields of document `i`.

  Specified by:
    `doc` in interface `Searchable`
  Throws:
    `CorruptIndexException` - if the index is corrupt
    `IOException` - if there is a low-level IO error
  See Also:
    `IndexReader.document(int)`

### doc

    public Document doc(int i,
                        FieldSelector fieldSelector)
                 throws CorruptIndexException,
                        IOException

  Deprecated.
  Description copied from interface: `Searchable`
  Get the `Document` at the `n`th position. The `FieldSelector` may be used to determine what `Field`s to load and how they should be loaded. NOTE: If the underlying Reader (more specifically, the underlying `FieldsReader`) is closed before the lazy `Field` is loaded an exception may be thrown. If you want the value of a lazy `Field` to be available after closing you must explicitly load it or fetch the Document again with a new loader.

  Specified by:
    `doc` in interface `Searchable`
  Parameters:
    `i` - Get the document at the `n`th position
    `fieldSelector` - The `FieldSelector` to use to determine what Fields should be loaded on the Document. May be null, in which case all Fields will be loaded.
  Returns:
    The stored fields of the `Document` at the nth position
  Throws:
    `CorruptIndexException` - if the index is corrupt
    `IOException` - if there is a low-level IO error
  See Also:
    `IndexReader.document(int, FieldSelector)`, `Fieldable`, `FieldSelector`, `SetBasedFieldSelector`, `LoadFirstFieldSelector`

### rewrite

    public Query rewrite(Query original)
                  throws IOException

  Deprecated.
  Description copied from interface: `Searchable`
  Expert: called to re-write queries into primitive queries.

  Specified by:
    `rewrite` in interface `Searchable`
  Throws:
    `IOException`

### explain

    public Explanation explain(Weight weight,
                               int doc)
                        throws IOException

  Deprecated.
  Description copied from interface: `Searchable`
  Expert: low-level implementation method Returns an Explanation that describes how `doc` scored against `weight`.

  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.

  Applications should call `Searcher.explain(Query, int)`.

  Specified by:
    `explain` in interface `Searchable`
  Throws:
    `IOException`

### main

    public static void main(String[] args)
                     throws Exception

  Deprecated.
  Exports a searcher for the index in args[0] named "//localhost/Searchable".

  Throws:
    `Exception`
