Q.  How can I search for a string in another string?

A.  You can use match() but if you don't need/want to look for a pattern,
use indexOf() like this:

	function isThere(hay_stack, needle) {
		return hay_stack.indexOf(needle) >= 0;
	}

	// Example use:
	function isFirefox() {
		return isThere(navigator.userAgent, 'Firefox');
	}
