Syntax

public class SearcherTaxonomyManager : ReferenceManager<SearcherTaxonomyManager.SearcherAndTaxonomy>, IDisposable

Constructors

SearcherTaxonomyManager(IndexWriter, bool, SearcherFactory, DirectoryTaxonomyWriter)

Creates near-real-time searcher and taxonomy reader from the corresponding writers.

Declaration

public SearcherTaxonomyManager(IndexWriter writer, bool applyAllDeletes, SearcherFactory searcherFactory, DirectoryTaxonomyWriter taxoWriter)

Parameters

Type	Name	Description
IndexWriter	writer
bool	applyAllDeletes
SearcherFactory	searcherFactory
DirectoryTaxonomyWriter	taxoWriter

SearcherTaxonomyManager(Directory, Directory, SearcherFactory)

Creates search and taxonomy readers over the corresponding directories.

NOTE: you should only use this constructor if you commit and call Lucene.Net.Search.ReferenceManager<G>.MaybeRefresh() (on the Lucene.Net.Index.ReaderManager) in the same thread. Otherwise it could lead to an unsync'd Lucene.Net.Search.IndexSearcher and TaxonomyReader pair.

Declaration

public SearcherTaxonomyManager(Directory indexDir, Directory taxoDir, SearcherFactory searcherFactory)

Parameters

Type	Name	Description
Directory	indexDir
Directory	taxoDir
SearcherFactory	searcherFactory
