search example from README doesn't work

[elf-pavlik]

When I try to run it I get empty array in solutions... we need to make sure that we put in README only exact examples from test suite!
While not that familiar with LevelGraph joins I also don't find it obvious what exactly we search for here, adding one sentence about intended results will make it clearer for everyone.

var nested = {
    "@context": {
        "name": "http://xmlns.com/foaf/0.1/name"
      , "knows": "http://xmlns.com/foaf/0.1/knows"
    }
  , "@id": "http://matteocollina.com"
  , "name": "matteo"
  , "knows": [{
        "name": "daniele"
    }, {
        "name": "lucio"
    }]
};

db.jsonld.put(nested, function(err) {
  db.join([{
      subject: db.v("person")
    , predicate: "http://xmlns.com/foaf/0.1/knows"
    , object: db.v("friend")
  }, {
      subject: db.v("friend")
    , predicate: "http://xmlns.com/foaf/0.1/knows"
    , object: "daniele"
  }], function(err, solutions) {
    // The solutions will be:
    // 1. { person: "http://matteocollina.com", friend: "_:abcde" }
    // 1. { person: "http://matteocollina.com", friend: "_:efghi" }
  });
});

I've just checked. Something weird is going on, but I'm not sure what.

It is supposed to return all friend of 'person' named 'Daniele'.

oh... in second part of join in predicate s/knows/name/ and still you get only one result since only you know her :)

[mcollina]

Oooh, right! GOSH. Thanks a million!!

[mcollina]

Daniele is a friend of mine (@dbottillo). I just hope he is not upset I used his name all over the place :P.

[mcollina]

Fix it, then!

[elf-pavlik]

i made an example search based on what i regularly look for, nowadays still using faceboogle...

Can I merge?

Or better, merge if you think it's fine. 👍 for me.
