Who's intent? That seems unnecessarily limiting to me. *IF* that
truly is the intent, I would suggest the LOC folks have some
misleading descriptions going on... from the web page,
"The design objective is that queries be human readable and writable,
and that the language be intuitive while maintaining the
expressiveness of more complex languages."

A typo? Boolean clauses aren't allowed in an any relation are they?

Yeah, I get the any and all, they're nice. When there are many of
them with only two terms though, and the need for prox's and not's
mixed in, that's not the cleanest solution. Supporting a construct
where an index+relation get projected upon a clause seems like a
no-brainer for the next version to me.
