Implement a encoded search to json-ld wrapper.

Implement a encoded search to json-ld wrapper.

An open question is encoded returns terms like "foo.bar" where
bar is an attribute of an object name for foo. However since
foo has no id associated with it, at best I would have a term with
a blank node.

For the moment I'm just deleting those terms. I'm not sure what a
better solution might be.
