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

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

Thanks for the quick and precise answer,
	fb are lowercased so indexed tokens don't match

They should not have to be *exactly* the same type... just compatible
types such that the indexed tokens match.
When you used the keywordTokenizer, was there other analysis such as
lowercasing going on?
