Query for specific stoichiometry


I am trying to get familiar with next-generation material project.
Unlike the legacy version, this new version does not seem to allow me to search materials systems using all wildcard formula. For example, I wish to find which materials in a specific space group have the formula A2B3C4. In the previous version, it was possible to use the search formula *2 *3 *4, but this does not work in new version. Is there any way to use all-wildcard formula in new version?

Thanks in advance for your help.
