Declaration
public IndexSearcher(Directory path)Parameters

IndexSearcher(Directory, Boolean)
Creates a searcher searching the index in the named directory. You should pass readOnly=true, since it gives much better concurrent performance, unless you intend to do write operations (delete documents or change norms) with the underlying IndexReader.
Declaration
public IndexSearcher(Directory path, bool readOnly)Parameters
| Type | Name | Description |
|---|---|---|
| Directory | path | directory where IndexReader will be opened |
| System.Boolean | readOnly | if true, the underlying IndexReader will be opened readOnly |
IndexSearcher(IndexReader)
Creates a searcher searching the provided index
Note that the underlying IndexReader is not closed, if IndexSearcher was constructed with IndexSearcher(IndexReader r). If the IndexReader was supplied implicitly by specifying a directory, then the IndexReader gets closed.
Declaration
public IndexSearcher(IndexReader r)Parameters
| Type | Name | Description |
|---|---|---|
| IndexReader | r |
