kCDAtomRestrictFreeSites1Finds compounds in which the selected atoms may contain a range of substituents up to the number specified plus the number of bonds as drawn. A value of zero finds a substituent count as drawn.
kCDAtomRestrictSubstituentsUpTo2Finds compounds in which the selected atoms may contain a range of substituents up to the number specified.
kCDAtomRestrictSubstituentsExactly3Finds compounds in which the selected atoms contain the exact number of substituents as specified, up to 15 substituents.
