Or is it not in relation with the search pattern facility incorporated in vi?
from vi man pages ( type man vi

Quote:

/ Read a string from the last line on the screen,
interpret it as a regular expression, and scan
forward for the next occurrence of a matching string.
The search begins when the user types a carriage
return to terminate the pattern; the search can be
terminated by sending SIGINT (or the user-designated
interrupt character).

Truly, if you are willing to learn UNIX even a minimum then it is far from being a waste of time learning vi basics (I installed a vi on my DOS pc at the time... and am completely lost when there is no vi...).
So start by reading the man pages and come back here for more explanation
There are plenty options in vi... even using s ( like sed...) for substitution...

gzgrep

GZGREP(1)						      General Commands Manual							 GZGREP(1)

NAME

       gzgrep, gzegrep, gzfgrep - search possibly compressed files for a regular expression

SYNOPSIS

       gzgrep [ grep_options ] [ -e ] pattern filename...

DESCRIPTION

       gzgrep is used to invoke the grep on compress'ed or gzip'ed files. All options specified are passed directly to grep.  If no file is speci-
       fied, 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  gzgrep  is  invoked as gzegrep or gzfgrep then egrep or fgrep is used instead of grep.  If the GREP environment variable is set, gzgrep
       uses it as the grep program to be invoked. For example:

	   for sh:  GREP=fgrep	gzgrep string files
	   for csh: (setenv GREP fgrep; gzgrep string files)
