As I understand, Lucene does a fair amount of caching of terms in memory without you having to specify anything.
But it's hard to see how your question relates. Remember that Lucene is finding *all* matching docs. So searching in a RAMdirectory and then searching in the file doesn't really seem possible since Lucene has to search the entire index every time to score the docs. It doesn't stop after the first hit, since the next hit may score higher. But I'm sure Lucene *does* cache portions of the index in RAM when possible, but I've never had occasion to dig into the details. Which leads me to ask "Why do you care?". Is there a specific situation you're trying to get better performance from or is this more of a background question? If you have a specific situation, please describe it in some detail so better minds than mine can give you a better response <G>....
