Fuzzy matching

FuzzyMatch.js

function fuzzy_match(text, search)
{
    /*
    Parameter text is a title, search is the user's search
    */
    // remove spaces, lower case the search so the search
    // is case insensitive
    var search = search.replace(/\ /g, '').toLowerCase();
    var tokens = [];
    var search_position = 0;

    // Go through each character in the text
    for (var n=0; n<text.length; n++)
    {
        var text_char = text[n];
        // if we watch a character in the search, highlight it
        if(search_position < search.length &&
          text_char.toLowerCase() == search[search_position])
        {
            text_char = '<b>' + text_char + '</b>';
            search_position += 1;
        }
        tokens.push(text_char);
    }
    // If are characters remaining in the search text,
    // return an empty string to indicate no match
    if (search_position != search.length)
    {
        return '';
    }
    return tokens.join('');
