Thank you phpbroker19 to allow us this bug fix :)
in my files, it was on line 470 not 471.
For _ck_ who is the real guy to thank, I continue my test report.
the "exact words" option has a strange behaviour : when the word we search is the last word in the topic_title, then it is not given in the results. It as if the end of the title was a character attached to the word. I forgot to say that I tested with the "located : 'only in titles' " option.
another strange bug : there are some empty posts given in results, or at least, the result show no post. And as there is only a link the the profile of the poster, this lead to a very strange result : we want to search a post, we click on a result, and we are on a profile page ...
I solved my layout problem (which appeared only in firefox, not in IE) by removing 'clear:left' in super-search-init.php line 594.
