Racket has an amazing amount of stuff in it, and sometimes it's not 
obvious what the built-in alternative to an SRFI is (when there is 
one).  I ran into the same issue as you, looking for functions to test 
and manipulate strings.  The racket built-in alternative is regular 
expression matching:

(regexp-match #rx"how" "Hello how are you?")

The best way I know of to find SRFI alternatives is to search the 
mailing list and then ask, just like you did.  My impression is that 
most SRFIs have Racket built-in alternatives.
