I'm using the RDKit Molecule Substructure Filter to filter molecules using small fragments (generated with the MoSS node) as queries. Everything works as desired 95% of the time but in certain cases the query is identified inside a fused ring (e.g. piridine found in a quinoline) which I would like to avoid.
