Hello, think you can find your answer in the IndexWriter API:
http://lucene.zones.apache.org:8080/hudson/job/Lucene-Nightly/javadoc/org/apache/lucene/index/IndexWriter.html The optional autoCommit argument to the constructors controls visibility of the changes to IndexReader instances reading the same index. When this is false, changes are not visible until close() is called. Note that changes will still be flushed to the Directory as new files, but are not committed (no new segments_N file is written referencing the new files) until close() is called. If something goes terribly wrong (for example the JVM crashes) before close(), then the index will reflect none of the changes made (it will remain in its starting state). You can also call abort(), which closes the writer without committing any changes, and removes any index files that had been flushed but are now unreferenced. This mode is useful for preventing readers from refreshing at a bad time (for example after you've done all your deletes but before you've done your adds). It can also be used to implement simple single-writer transactional semantics ("all or none").
