I didn't see a response.  So:

% ./timeit
query(not somewordIknowisnotinmyindex) [hits=243756] took 00.381902 
seconds
query(not(a and not a)) [hits=243756] took 00.631291 seconds
% ./timeit
query(not somewordIknowisnotinmyindex) [hits=243756] took 00.309732 
seconds
query(not(a and not a)) [hits=243756] took 00.530991 seconds
% ./timeit
query(not somewordIknowisnotinmyindex) [hits=243756] took 00.233165 
seconds
query(not(a and not a)) [hits=243756] took 00.501219 seconds
% ./timeit
query(not somewordIknowisnotinmyindex) [hits=243756] took 00.247380 
seconds
query(not(a and not a)) [hits=243756] took 00.529831 seconds
