How to pass information to backend?

How to pass information to backend?

[Kai.Grossjohann]

I have written nnir.el which allows you to search your mail.  It is a
`virtual backend'.  The group name is interpreted as the query (and
vice versa), and nnir.el creates a virtual group with the query
results in it.

I think passing information between Gnus and the backend via the group
name is a suboptimal solution.  For example, queries might get quite
long, and long group names are difficult to show in the mode line.

But mostly my problem with this is that I feel I am misusing the group
name for something it was never intended for.

Have you got better suggestions on how to communicate between Gnus and
the backend?

Pass the data to the backend in the `defs' parameter of
`nnfoo-open-server'?

Well, most backends have a defvoo'd variable that says, er, something, 
and then Gnus creates a group with

(nnfoo "" (nnfoo-that-thing "set-to-something") ... )

as the server.
