Sorry for the late reply.
There is no reference or documentation for FP2 fingerprint other than
what is in the code. It is similar in principle to the Daylight
fingerprint, indexes fragments up to 7 atoms, excluding some single
atom fragments, and whether they are rings. It is sensitive to the
bond aromaticity and order, but only the atomic number of atoms. It is
hashed into 1021 bits but is output at 1024 bits.
