\b is a word boundary character in a regular expression. /i is ignore case. Replace best with your search word.

var string="Stackoverflow is the BEST";
var searchText = "Stackoverflow";
var re = new RegExp("\\b"+searchText+"\\b",'i');
if ( re.test(string)){
  alert('match');
}else {
  alert('not match');
}

I know this is a bit more verbose, but why not something like:

var exists = function (content, q) {
    var result = content.split(" ").filter(function(item) {
        return item.toLowerCase() === q.toLowerCase(); 
    });
    return result.length > 0;
};

Here is the fiddle.

Use a regex check. Google for word boundaries to learn more about them.

/\bbest\b/i.test("Stackoverflow is the BEST")

\b is a word boundary character in a regular expression. /i is ignore case. Replace best with your search word.

use .test()

var string="Stackoverflow is the BEST";
var result= /s/i.test(string);
alert(result);
