How to exactly match a given string in a sentence.

For example if the sentence is
var sentence = A Google wave is basically a document which captures a communication

and the given string is
var inputString= Google Wave. I need to check the exact presence of Google Wave in the above sentence & return true or false.

I tried

if(sentence.match(inputString)==null){

            alert(No such word combination found.);

        return false;

        }

This works even if someone enters Google W. I need a way to find the exact match. Please help

OP wants to return false when do search with Google W.

I think you should use word boundary for regular expression.

http://www.regular-expressions.info/wordboundaries.html

Sample:

inputString = \b + inputString.replace( , \b \b) + \b;

if(sentence.toLowerCase().match(inputString.toLowerCase())==null){

    alert(No such word combination found.);

}
