Hi!
Thanks for the immediate reply, i just fixed it though!
apparently the QueryParser consructs  a query regardless of the 
analyzer's tokens
I simply created my own booleanQuery by calling my custom analyzer and 
treating the user inputed query text as a stream.
The result works perfectly!
Thank you again for your time and patience! :-)
