please confirm: pseudo join queries can only be performed on fields of exactly the same type

[Matteo Grolla]

Hi,
        I tried performing a join query 
        {!join from=fA to=fB}
        where fA was string and fB was text  using keywordTokenizer

        it doesn't work, but it does if either fields are both string or both 
text.
        
        If you confirm this is the correct behavior I'll update the wiki

thanks
