Aha aha... how could I miss that :) Thanks for answering!
Quoting Dirk Kirsten <d...@basex.org>:
Hi Guiseppe, well, BaseX is smart and figures out that 6-2 is 4 ;) When you just use the numbers, XQuery will assume it is an xs:integer, so accordingly it will compute the result. If you want to use it as string you have to enclose it in "", i.e. "/cluster/home/g/results2/" || "6-2" || ".xml" although the concatenation in this case would not be necessary.
