When we do full rebuilds we build into a new Directory. When it is ready we create a commit lock on the active directory to block new searches, sleep for a half-second to let exisitng searches finish, and then copy the newly built directory over the old one. This seemed to avoid file system lock issues on windows and unix and ongoing searches just wait for the commit lock to be released.
-Lars
To create the commit lock:
FSDirectory activeDirectory;
Lock searchLock;
try {
searchLock = activeDirectory.makeLock(IndexWriter.COMMIT_LOCK_NAME);
... do the copy
} finally {
searchLock.release();
}
