Using the string Match with options! [duplicate]

Question

Here is what I want to do:

I have a list of strings for example

s={"red carpet","red box","black carpet","black box"}

I want to use something like

Select[s, StringMatchQ[#, "red"] &] (*to get an output*)

{"red carpet","red box"}

thx in advance for your help

Try this Select[s, StringMatchQ[#, ___ ~~ "red" ~~ ___] &]!! — PlatoManiac, Jan 28, 2015 at 13:04
This is using the solution I have you in a comment on your last question. When you receive a solution, it's a good idea to try to understand how it works. Start by looking up the functions in the documentation. Reading up on StringMatchQ would have immediately solved this problem. — Szabolcs, Jan 28, 2015 at 19:01

You were looking for StringFreeQ I think:

Select[s, ! StringFreeQ[#, "red"] &]

Another way, StringCases with a regular expression:

StringCases[s, RegularExpression[".*red.*"]] // Flatten
