Loading an index into memory?

Ruby Apps Ferret

Is there a way to tell Ferret (or AAF) to read an entire index into
memory, for faster searching? I have small index (3-4 MB) that could be
kept in memory. Or does Ferret do that automatically?

Thanks,

Ferret has an implementation if the Directory interface [1] for
in-memory
storage, however you won’t gain much speed (if any) by using it, since
most operating systems will keep the index in file system buffers anyway
once it has been used the first time.
