OData specifies 10 logical operators[1]. I'm not saying that list is
necessarily complete, but it's enough to be a good distance within the
80/20 rule. Would you say that having one predicate per such operator
is too much?

I'm not sure IRI templates are expressive enough to solve the problem
at hand. It would be awesome if I could stuff an IRI template inside
my hydra:ApiDocumentation that supported the full range of OData Query
Options[2] (which is what many of my APIs support), but I don't think
that's possible.

Yes. Use OData Query Options. :)
