The ''Molecular Query Language'' ('''MQL''') was designed for allowing more complex and problem specific search methods. The [[query language]] is based on an [[extended Backus–Naur form]] (EBNF) using [[JavaCC]]. In contrast to [[Smiles_arbitrary_target_specification|SMARTS]] queries this allows the specification of spatial and physicochemical properties of atoms and bonds. Furthermore can it be easily extended to non-atom-based graphs, called reduced feature graphs.
