Description
Custom Lookups look great, however, I find the documentation terse. Example: no explanation what
lhs, lhs_params = self.process_lhs(qn, connection)
is exactly.
The explanation: "lhs
The lhs (left-hand side) of a lookup tells us what we are comparing the rhs to. It is an object which implements the query expression API. This is likely to be a field, an aggregate or a subclass of Transform.
does not explain" does not explain what lhs_params might be. Also a search on "process_lhs" on complete Django website only points to this page (no other pages).
