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 AutoCloseable

  Specified by:

  close in interface Closeable

  Specified by:

  close in interface Searchable

  Throws:

  IOException

• docFreq

  public int docFreq​(Term term)

  Throws:

  IOException

• 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.

• 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,

                             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 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 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

  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
