Hmm, searching was probably a bad subject choice, querying is more accurate....
I was thinking for more complex queries on children, where you want to query on
multiple attributes/columns, e.g. for a particular invoice, get all the line
items that are in 1 or more categories and have a quantity > 2, that sort of
thing. Kind of inspired by the statement 'SQLAlchemy allows the creation of
select statements from not just Table objects, but from a whole class of objects
that implement the Selectable interface'. Or maybe it's closer to a dynamic
version of custom join conditions.
I know it's not possible atm, but on the surface it seems a useful ability to
have, but maybe that's just my warped sense of useful!
