Delete all documents in the index.

This method will drop all buffered documents and will remove all segments from the index. This change will not be visible until a {@link #Commit()} has been called. This method can be rolled back using {@link #Rollback()}.

NOTE: this method is much faster than using deleteDocuments( new MatchAllDocsQuery() ).

NOTE: this method will forcefully abort all merges in progress. If other threads are running {@link #Optimize()} or any of the addIndexes methods, they will receive {@link MergePolicy.MergeAbortedException}s.
