string in a string

Hi,
I m working on a solution which wud script the following scenarios but not quite getting to work 100%.

Case1(very simple)
S1: HELLO_WORLD_HOW_ARE_YOU
S2: HELLO
Easy n simple soln wud be : echo "$S1" | grep "$S2"

Case2:
S1:HELLO_WORLD_HOW_ARE_YOU
S2:HELLO_HOW_ARE_YOU
In this case, above soln would not return TRUE though my S2 is indeed part of S1 but S2 is basically not Continuous.
I am looking for a soln which wud throw a 1 in the above case.

Case3:
S1:HELLO_WORLD_HOW_ARE_YOU
S2:HELLO_JOHN or HI_WORLD
Even this shud return a TRUE.

Basically my intention is, even if a particular pattern in S2(need not be the entire string S2) matches somewhere in S1, I shud get a TRUE .
Plz remember, both S1 and S2 are not Fixed length !

Any ideas?.
