I am reading lucene in action 2,there is some question about it. When a flush occurs, the writer creates new segment and deletion files in the Directory. However, these files are neither visible nor usable to a newly opened IndexReader until the writer commits the changes. It's important to understand this difference. Flushing is done to free up memory consumed by buffered changes to the index, whereas committing is done to make all flushed changes persistent and visible in the index.
Why Flushing does not make all flushed changes persistent even if it had created new segment? Flushing does not mean flush any change to disk? --------------------------------------------------------------------- To unsubscribe, e-mail: java-user-unsubscr...@lucene.apache.org For additional commands, e-mail: java-user-h...@lucene.apache.org
