Get returns triples which start with the search criteria

[richorama]

Hi,

When I do a search for triples, I get back all triples that start with the supplied criteria. I would expect to see only triples that exactly match the criteria.

Illustrated by this repl session:

$ node
> var db = require('levelgraph')('test');
> db.put({subject:'a', predicate:'b', object:'c'});
> db.put({subject:'a1', predicate:'b1', object:'c1'});
> db.put({subject:'a2', predicate:'b2', object:'c2'});
> db.get({subject:'a'}, console.log);

[ { subject: 'a1', predicate: 'b1', object: 'c1' },
  { subject: 'a2', predicate: 'b2', object: 'c2' },
  { subject: 'a', predicate: 'b', object: 'c' } ]

However, I would expect (like!) this behaviour:

> db.get({subject:'a'}, console.log);

[ { subject: 'a1', predicate: 'b1', object: 'c1' } ]

Is there a way to configure this?

Thanks,

Richard.

Actually it's a bug, but it's easy to fix.
I think it's enough to change the range pattern in
https://github.com/mcollina/levelgraph/blob/master/lib/utilities.js#L107-L108

to:

{
  start: key + ':',
  end: key + '\xff',
  fillCache: true
}

I'll fix it asap.

Thanks!
