I'd write a shutdown method that calls close() in a controlled manner and invoke it at 23:55. You could also call commit() at whatever interval makes sense to you but if you carried on killing the JVM you'd still be liable to lose any docs indexed since the last commit.
This is standard stuff just like any file system or database. If you don't commit or close you are likely to lose data. -- Ian.
