function highlight(str, term) {
--------------------------------- ADDED CHANGES ----------------------------------------------------------
term = term.replace(/^\s+|\s+$/g, '') //replace trailing spaces
term = term.replace(/\s\s+/g, '|') //replace all spaces, tabs, newlines by | => regex OR,
//instead of using "term" as a single word

            var highlight_regex = new RegExp('(' + term + ')', 'gi');
            return str.replace(highlight_regex,
                '<span class="highlight">$1</span>');
        };
