Under ideal conditions - maybe. But if each file is more than 1 MB, it
is barely possible to even read this amount of data in just 10 seconds
(assuming around 80 MB/s and 1000 MB of data to be searched).

Even using a simple word index (word plus the name of the file(s) and
the position(s) where the word is located) would be the better solution.
