hi, maybe you can use the -A an d -B option of grep, i put and example :
texto= is a file for example, has 6lines
man grep:
-A NUM, --after-context=NUM
Print NUM lines of trailing context after matching lines.
Places a line containing -- between contiguous groups of
matches.
-B NUM, --before-context=NUM
Print NUM lines of leading context before matching lines.
Places a line containing -- between contiguous groups of
matches.

Code:
$more texto
line1
line2
line3
line4
line5
line6
$grep -A 2 -B 1 "line3" texto
line2
line3
line4
line5
$grep -A 1 -B 2 "line3" texto
line1
line2
line3
line4

NAME
gnome-search-tool - the GNOME Search Tool SYNOPSIS
gnome-search-tool [options] or select Search for Files... from a Main Menu or from the Places menu in a Menu Bar DESCRIPTION
GNOME Search Tool is a utility for finding files on your system. To perform a basic search, you can type a filename or a partial filename, with or without wildcards. To refine your search, you can apply additional search options. GNOME Search Tool uses the find, grep, and locate UNIX commands. The case sensitivity of the search depends on your operating system. For example, on Linux, the find, grep, and locate commands support the -i option, so all searches are case-insensitive. For full documentation see the GNOME Search Tool online help. OPTIONS
--help Show help message --named=STRING Set the text of "Name contains" search option --path=PATH Set the text of "Look in folder" search option --sortby=VALUE Sort files by one of the following: name, folder, size, type, or date --descending Set sort order to descending, the default is ascending --start Automatically start a search --contains=STRING Select and set the "Contains the text" search option --mtimeless=DAYS Select and set the "Date modified less than" search option --mtimemore=DAYS Select and set the "Date modified more than" search option --sizemore=KILOBYTES Select and set the "Size at least" search option --sizeless=KILOBYTES Select and set the "Size at most" search option --empty Select the "File is empty" search option --user=USER Select and set the "Owned by user" search option --group=GROUP Select and set the "Owned by group" search option --nouser Select the "Owner is unrecognized" search option --notnamed=STRING Select and set the "Name does not contain" search option --regex=PATTERN Select and set the "Name matches regular expression" search option --hidden Select the "Show hidden and backup files" search option --follow Select the "Follow symbolic links" search option --mounts Select the "Exclude other filesystems" search option AUTHOR
