Search result - Order function has some problem in some conditions

Overview: if you search record for title, you will see twice the same record in the result list, because it contains two title headings that begins with the same word (one in tag 245 and one in tag 240). The same occurs if you search the record for Name: I will see the same item twice, because it has a Name heading in tag 100 and another one in tag 700, that begins with the same word.
