Subject: RE: [search-ws] multiple query types

I'd suggest

(5) Use (2) and the server can define an additional local name for the
parameter in their Explain record. (reserving 'query' for CQL). This
would be like Context Sets and their local names.  We'd have an
unambiguous, interoperable version of the parameter name and allow
servers to define something shorter and pithier.
