dis/con-junctive queries would be nice #184

(a) Presently in query parameters using the same property-chain more
than once is explicitly disallowed. This means that for multi-valued
properties P the natural conjunction P=V1&P=V2 cannot be used to find
items with both (?item P V1) and (?item P V2).

(b) Relatedly there's no way to ask for P=V1 OR P=V2.

Note that the text search capability (_search and the text:query property)
uses a query sublanguage with AND, OR and NOT capabilities, but this
does not work for non-text property values.
