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 nth position. The FieldSelector may be used to determine what Fields 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 nth 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

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
