Magma's indices are based on integer hashes: all objects who index attribute has the same value will have the same hash value.
At this point, finding the object in the index becomes a linear search.

By definition boolean object hash to on of two values, 0 or 1

I managed to minimise the impact of this restriction by hashing false to the range 0 - 32767 and true to 32768-65535.
Finding object was no quicker, but inserting object was much, much quicker.
