True, but won't it stop looking when it has found 8 matches?
i.e. there could be more "sample"s later in the buffer?
==
One could try anchoring the last sample:
(sample.*){7,7}(sample.*$){1,1}
but I think that would suffer from the same problem as the negative
look-ahead.
It may be tricky stopping the matcher from working its way past the leading
samples.

Also,
(sample.*){8,8} will match exactly 8 occurrences.
