should be
g.v('12:615')
note the lower case "v" and the () instead of []

the

from them, since this does not exist you get nulls.
I would beware using g.V since it will return ALL vertices
http://orientdb.com/docs/2.0/orientdb.wiki/Graph-Database-Tinkerpop.html
Has some info that will be useful to you.
Say you have a class
MyV
with indices
MyV.myid UNIQUE_HASH_INDEX STRING
MyV.kind NOTUNIQUE STRING
then
> g.getVertices("MyV.kind", "baz")._()
will get you a gremlin pipe of everything in the index MyV.kind
getVertices needs the "._()" in order to turn the result into a gremlin
pipeline.
to get one vertex you can do
> g.getVertexByKey("MyV.myid", "foobar")
or
> g.getVertices("MyV.myid", "foobar")._()[[0] //will error if doesn't exist
If you do
> g.getVertices("myid", "foobar")
orientdb should check if you have an index "V.myid" and use that if it
exists.
It is kinda tricky telling if the indices are used sometimes.
Hope this helps!
