BTW, what nobody said yet is that both Icicles and Helm implement buffer
searches that allow negation, i.e., have built in what you described in
your prior post.  Before you reinvent the wheel ... maybe you find one
of these sufficient.

In Icicles' search, use the normal candidate exclusion mechanism.

In helm, use helm-occur and enter e.g. "rx1 !rx1rx2" to match lines that
match regexp rx1, but that do not match regexp rx1 followed by regexp
rx2  ("!" just means "negation").


Michael.
