Are you suggesting something declarative? E.g., a list of FQCNs in your config file?
Might work, but I still prefer mandating the type to query on, on a per-query basis.
I'm also not a big fan of listing FQCNs, but for example when doing a
"FROM" in JPA-QL you can target a supertype and be returned subtypes;
in our case you'd have to list all subtypes as well.
(i.e. "FROM java.lang.Object" is a valid query).
Or does Reflections provide some cool way to find all subtypes of a
class? Even if it's a bit expensive, we already cache all new class
processing as for each new type we have to restart the Search engine
which is quite expensive anyway.
