Hello, The kind sir below recommended the RAMDirectory for loading an on-disk index into memory (the entire data) and using IndexSearcher off that. It seemed to worked very well.
On one index, I am seeing no speed change when flipping between RAMDirectory IndexSearcher and file system version. Creating the RAMDirectory from the on-disk index only takes 0.09 seconds. It appears it is not loading the data into memory, but maybe just the file names of the index? How can I load an on-disk index - the data - into memory and run searches there? thanks for any help. you guys are awesome!
