Answer 2

Another way of converting raw string to a RegExp (with flags) is described below.
var raw = "\bart\b"; //regex pattern in a raw string format
var reg = new RegExp(raw, "gi") //converting the raw string to a regexp with the flags global and insensitive.

Now you can use it for string.search() method. Hope this helped more :)
