Answer 1

The easiest way with an exact search string is to skip regular expressions and just use indexOf, e.g.:

// String to be searched
var s = "Here is a link."

// String to find
var searchString = "";

// Final match
var matched = "";

var c = s.indexOf(searchString);
if (c >= 0)
{
    // Returns the portion not including the search string;
    // in this example, "Here is a link". If you want the
    // search string included, add the length of the search
    // string to c.
    matched = s.substring(c);
}
