Dear Chandra,
Please use the client/server architecture of BaseX if you want to run
multiple queries in parallel. After all, it's also possible to do
multiple queries without a running server instance, but it's usually
not possible to make it work without spending more time with the BaseX
code.
Please take your time and have a look at our documentation, it should
give you some more instructions (e.g. [1,2,3]).
All the best,
Christian
