OK, I just watched Brett Slatkin's I/O talk [1] and he mentions "cross product" a couple of times, so it seems that the use of the word "permutation" in the docs is incorrect; the number of index entries is indeed proportional to the Cartesian product, rather than "permutations" which would lead to

If you want to compare lowercase you have to store the value lowercase in the object. GQL != SQL You can't do more then described on the GQL reference page. You have to traverse (get) all you current objects and make the field login lowercase and store the object back and as such update the index
