There are days I like to pull my hair out and create a dynamic 4D map that holds a list of records. 🤯

Yes there's a valid reason to build this map, generally I'm against this kind of depth 2 or 3 is usually where I draw the line, but I need something searchable against multiple indexes that doesn't entail querying the database over and over again as it will be used against large dynamic datasets, and the only thing I could come up with was a tree to filter down on as required.
