Syntax

public abstract class BaseLuceneSearchProvider : IFullTextSearchProvider, IDisposable, IConfigurationSerializable

Remarks

Derived Implementations may only need to call the base constructor as the LuceneSearchProvider does but if you've implemented custom indexing you may need to extend more of this class.

Constructors

BaseLuceneSearchProvider(LuceneVersion, Directory, Analyzer, IFullTextIndexSchema)

Creates a new Base Lucene Search Provider.

bool	autoSync	Whether the Search Provider should stay in sync with the underlying index.

Properties

IsAutoSynced

Gets whether this search provider is always seeing the latest state of the index.

Declaration

public bool IsAutoSynced { get; }

Property Value

Type	Description
bool

Methods

Dispose()
