C# Класс Lucene.Net.Index.CheckIndex

Basic tool and API to check the health of an index and write a new segments file that removes reference to problematic segments.

As this tool checks every byte in the index, on a large index it can take quite a long time to run.

WARNING: this tool and API is new and experimental and is subject to suddenly change in the next release. Please make a complete backup of your index before using this to fix your index!

Метод	Описание
CheckIndex ( Lucene.Net.Store.Directory dir ) : System	Create a new CheckIndex on the directory.
CheckIndex_Renamed_Method ( ) : Status	Returns a Status instance detailing the state of the index. As this method checks every byte in the index, on a large index it can take quite a long time to run. WARNING: make sure you only call this when the index is not opened by any writer.
CheckIndex_Renamed_Method ( List onlySegments ) : Status	Returns a Status instance detailing the state of the index.
FixIndex ( Status result ) : void	Repairs the index using previously returned result from CheckIndex. Note that this does not remove any of the unreferenced files after it's done; you must separately open an IndexWriter, which deletes unreferenced files when it's created. WARNING: this writes a new segments file into the index, effectively removing all documents in broken segments from the index. BE CAREFUL. WARNING: Make sure you only call this when the index is not opened by any writer.
SetInfoStream ( StreamWriter @out ) : void	Set infoStream where messages should go. If null, no messages are printed
