Not really a BBEdit solution, but "return all lines which contain
such-and-such a string" is the most trivial application of the `grep`
command:
$ cat > logfile
user1 did something
user2 did something else
yet another thing was done by user1
something else was done by user3
^D
$ grep user1 logfile > newlogfile
$ mv newlogfile logfile
$ cat logfile
user1 did something
yet another thing was done by user1
Sometimes the command line is actually much simpler than using BBEdit
(which would presumably need really complex line-oriented search-and-
replace pattern to accomplish the same task)...
(type "man grep" to learn about more advanced usage of grep)

Hey all
I have a rather large (~20MB) log file, and I want to delete all the
lines that *don't* contain a string (in this case, a username).
I'm sure there is some kind of greppy goodness that can be applied to
accomplish this, but I don't know the first thing about grep. :-/
Any suggestions? Thank you!
Thomas.
