When i grep for a pattern the search results comes up with matching lines(some before the pattern and some after)...how can i limit the search so that it shows only the lines after the pattern specified
You must have provided some extra flags for grep. Show us the grep command that you issued. GNU grep talks about
Surely you must be have provided both the flags.

GREP(1) General Commands Manual GREP(1)NAME
grep, g - search a file for a pattern
SYNOPSIS
grep [ option ... ] pattern [ file ... ]
g [ option ... ] pattern [ file ... ]
DESCRIPTION
Grep searches the input files (standard input default) for lines that match the pattern, a regular expression as defined in regexp(7) with
the addition of a newline character as an alternative (substitute for |) with lowest precedence. Normally, each line matching the pattern
is `selected', and each selected line is copied to the standard output. The options are
-c Print only a count of matching lines.
-h Do not print file name tags (headers) with output lines.
-e The following argument is taken as a pattern. This option makes it easy to specify patterns that might confuse argument parsing,
such as -n.
-i Ignore alphabetic case distinctions. The implementation folds into lower case all letters in the pattern and input before interpre-
tation. Matched lines are printed in their original form.
-l (ell) Print the names of files with selected lines; don't print the lines.
-L Print the names of files with no selected lines; the converse of -l.
-n Mark each printed line with its line number counted in its file.
-s Produce no output, but return status.
-v Reverse: print lines that do not match the pattern.
-f The pattern argument is the name of a file containing regular expressions one per line.
-b Don't buffer the output: write each output line as soon as it is discovered.
Output lines are tagged by file name when there is more than one input file. (To force this tagging, include /dev/null as a file name
argument.)
Care should be taken when using the shell metacharacters $*[^|()= and newline in pattern; it is safest to enclose the entire expression in
single quotes '...'. An expression starting with '*' will treat the rest of the expression as literal characters.
G invokes grep with -n and forces tagging of output lines by file name. If no files are listed, it searches all files matching
*.C *.b *.c *.h *.m *.cc *.java *.cgi *.pl *.py *.tex *.ms
