C# Класс Lucene.Net.Index.DocumentsWriter

Called if we hit an exception at a bad time (when updating the index files) and must discard all currently buffered docs. This resets our state, discarding any docs added since last flush.

Returns true if the caller (IndexWriter) should now flush.

Closes the current open doc stores an returns the doc store segment name. This returns null if there are * no buffered documents.

Build compound file for the segment we just flushed

Reset after a flush

Does the synchronized work to finish/flush the inverted document.

Flush all pending docs to a new segment

Returns a free (idle) ThreadState that may be used for indexing this one document. This call also pauses if a flush is pending. If delTerm is non-null then we buffer this deleted term after the thread state has been acquired.

Returns true if any of the fields in the current buffered docs have omitTermFreqAndPositions==false

Called whenever a merge has completed and the merged segments had deletions

Set flushPending if it is not already set and returns whether it was set. This is used by IndexWriter to trigger a single flush even when multiple threads are trying to do so.

If non-null, various details of indexing are printed here.

Set how much RAM we can use before flushing.
