Examples:

construct_query_for_rel [[:has_model, "info:fedora/afmodel:ComplexCollection"], [:has_model, "info:fedora/afmodel:ActiveFedora_Base"]], 'OR'
# => _query_:"{!raw f=has_model_ssim}info:fedora/afmodel:ComplexCollection" OR _query_:"{!raw f=has_model_ssim}info:fedora/afmodel:ActiveFedora_Base"

construct_query_for_rel [[Book.reflect_on_association(:library), "foo/bar/baz"]]
