Constructor SearcherManager

SearcherManager(IndexWriter, Boolean, SearcherFactory)

Creates and returns a new SearcherManager from the given IndexWriter.

Declaration
public SearcherManager(IndexWriter writer, bool applyAllDeletes, SearcherFactory searcherFactory)
Parameters
Type Name Description
IndexWriter writer

The IndexWriter to open the IndexReader from.

System.Boolean applyAllDeletes

If true, all buffered deletes will be applied (made visible) in the IndexSearcher / DirectoryReader. If false, the deletes may or may not be applied, but remain buffered (in IndexWriter) so that they will be applied in the future. Applying deletes can be costly, so if your app can tolerate deleted documents being returned you might gain some performance by passing false. See OpenIfChanged(DirectoryReader, IndexWriter, Boolean).

SearcherFactory searcherFactory

An optional SearcherFactory. Pass null if you don't require the searcher to be warmed before going live or other custom behavior.

SearcherManager(Directory, SearcherFactory)

Creates and returns a new SearcherManager from the given Directory.

Declaration
public SearcherManager(Directory dir, SearcherFactory searcherFactory)
Parameters
Type Name Description
Directory dir

The directory to open the DirectoryReader on.

SearcherFactory searcherFactory

An optional SearcherFactory. Pass null if you don't require the searcher to be warmed before going live or other custom behavior.
