var is lower case
Strings can be delimited with " or ' but not with “, don't use curly quotes.
The search method expects a regular expression (although it will try to convert a string if it gets one)
If you want a simple string match, then indexOf is more efficient then search.
Both search and indexOf return the index of the first match (or -1 if it doesn't find one), not a boolean.

As an aside, that Doctype will trigger quirks mode, so never use it in a real HTML document.

var result = "<!DOCTYPE HTML PUBLIC -//W3C//DTD HTML 4.01 Transitional//EN html><head<title>Hey i am here</title>"

if (result.indexOf("Hey i am here") >= 0) {
    alert('found');
} else { 
    alert('NOT found'); 
}

Search method returns the position of the match, or -1 if no match is found. Not true or false.

I thinks you need to use an .indexOf function.

so your if statement would be

if (results.indexOf('Hey i am here') != -1) {
   alert('found');
} else { alert('NOT found'); }

There are a lot of ways to do this: See here
