            $search = $_POST['search'];





                        $stemmer = new Stemmer;
                        $stemmed_string = $stemmer->stem($search);

                        $clean_string = new cleaner();
                        $stemmed_string = $clean_string->parseString($stemmed_string);


                        $split = preg_split("/[ ]/ ",$stemmed_string);

It seems your query has an extra opening parenthesis in the WHERE clause:

"SELECT ... FROM articles WHERE (( ... ) OR ( ... ) GROUP BY ..."

So at line 42 remove the first parenthesis. I'm not sure this will fix your problem, if not post the line error, bye!

I think the problem is here
(line 28)

foreach ($split as $array => $value) {
        if (strlen($value) > 3) {
            continue;
            }
        $new_string = ''.$value.' ';
        }

$new_string will only exist if $array contains a value longer than 3 chars
