I'm updating nearly continuously (probably average about every 10 seconds). I don't explicitly close the IndexSearcher objects I create, as I share them across threads, but do leave them to be garbage collected. I ran into index corruption issues when I explicitly closed them, since I don't have any code keeping track of how many threads might be using a given IndexSearcher.
I wonder if it's worth the effort of adding that code in, or can I be ensured that when the IndexSearcher objects are garbage collected the file handles will be released? -- m@ > How often are you updating your index?
