Federated Search on Windows, is best left alone. I have a test setup
on the other machine, 1 million files indexed by the indexer, and the
time to produce a search result varies from five seconds to sixty seconds.
It would take a hundred lines of posting, to explain how to tune it,
and even when tuned, it`s not a wonder-pony. It has pathological behavior,
that interacts with how you use the machine (your searches slow down,
if you force the thing to re-index areas with new files).
*******
There are third party tools for search.
There is Voidtools Everything.exe and Mythic Software Agent Ransack
(free version).
If you use an SSD instead of a Hard Drive, that completes the set
and gives you something useful.
