--- Comment #5 from John Mark Vandenberg jayvdb@gmail.com --- geulimit=1 says the client wants 1 only record.
The MW API isnt returning one record. It is moving the cursor forward by one and returning zero records.
It feels like MW is interpreting 'geulimit=1' as 'only look at one record, and return the data if it meets the request criteria'
