Well, grep is certainly the best way to search through a file... combined with options that allow you to only display the name of the files that contain the search string, it'd be hard to duplicate.
You should be able to search an entire filesystem using a string like this:
The "file" command will skip directories, the "-l" option to grep will only tell you which files the string is in, and the "2>/dev/null" will send any errors (as a result of something like trying to grep a file that you don't own, or don't have permissions to look at) to the null device - a suitable place for them!

zgrep
ZGREP(1) General Commands Manual ZGREP(1)NAME
zgrep - search possibly compressed files for a regular expression
SYNOPSIS
zgrep [ grep_options ] [ -e ] pattern filename...
DESCRIPTION
Zgrep invokes grep on compressed or gzipped files. These grep options will cause zgrep to terminate with an error code:
(-[drRzZ]|--di*|--exc*|--inc*|--rec*|--nu*). All other options specified are passed directly to grep. If no file is specified, then the
standard input is decompressed if necessary and fed to grep. Otherwise the given files are uncompressed if necessary and fed to grep.
If the GREP environment variable is set, zgrep uses it as the grep program to be invoked.
EXIT CODE
2 - An option that is not supported was specified.
