I see. Can you remark on how hard it might be to specify a parameter in the appropriate query methods which would designate a maximum execution time before the query is cleanly aborted (in "wall clock time")? This would be in a client/server context.
Phil At http://docs.basex.org/wiki/Options#Server_options%C2%A0is mentioned server wide option TIMEOUT, which can limit time for query execution. I wonder, if there is any way to specify this per query. Jan
....exactly; this option will do exactly what you need.
Thanks, Christian

as far as I can judge, XQuery expressions are too heterogeneous to provide realistic cost estimations. While our query compiler has some notion of "costs", those values are all relative, and used to select the (presumably) cheapest query plan or index access.
