Code

public function op_word($field) {
    $where = $this->operator == 'word' ? db_or() : db_and();
    // Don't filter on empty strings.
    if (empty($this->value)) {
        return;
    }
    preg_match_all('/ (-?)("[^"]+"|[^" ]+)/i', ' ' . $this->value, $matches, PREG_SET_ORDER);
    foreach ($matches as $match) {
        $phrase = FALSE;
        // Strip off phrase quotes.
        if ($match[2][0] == '"') {
            $match[2] = substr($match[2], 1, -1);
            $phrase = TRUE;
        }
        $words = trim($match[2], ',?!();:-');
        $words = $phrase ? array(
            $words,
        ) : preg_split('/ /', $words, -1, PREG_SPLIT_NO_EMPTY);

            $where->condition($field, '%' . db_like(trim($word, " ,!?")) . '%', 'LIKE');
        }
    }
    if (!$where) {
        return;
    }
    // Previously this was a call_user_func_array but that's unnecessary as
    // Views will unpack an array that is a single arg.
