I guess it depends upon your goal. If you're asking what the difference between writing to a RAMDirectory *then* flushing to an FSDIrectory, I don't believer there's much, if any. As I remember (and my memory isn't always...er...accurate), there's been discussion on this thread by those who know that underneath the covers an FSDirecotyr uses a RAMDirectory for a while, then flushes it to disk.
If you're asking what the difference between a RAMDirectory is and an FSDirectory, that's another story. Erick On 2/28/07, WATHELET Thomas <[EMAIL PROTECTED]> wrote:
I don't really understand the difference between using the ramDirectory and using IndexWriter. What's the difference between using ramDirectory instead of using IndexWriter with those properties set to: setMergeFactor(1000);setMaxMergeDocs(10000);setMaxBufferedDocs(10000);
