Code

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);
    $placeholder = $this->placeholder();
    foreach ($words as $word) {
      $where->where($field . " LIKE $placeholder", array($placeholder => '%' . db_like(trim($word, " ,!?")) . '%'));
    }
  }

  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.
  $this->query->add_where($this->options['group'], $where);
