It appears the following searches for the individual characters.

You'll first need to unescape the HTML in the pattern:

var i = text.indexOf(decodeHTML('»'));

function decodeHTML(s) { // e.g. using jQuery
    return $('<div>' + s + '</div>').text();
}

var i = text.indexOf('\273')

would search for the actual character.

Try looking at the html directly.

document.getElementById('search').innerHTML.indexOf('&raquo;')
