Karthik,
You can index the nodes you are interested in as start and/or end-nodes of your
traversal and then retrieve them via the index.
// to add them
gDB.index().forNodes("indexName").add(node,"key","value");
nodeIndex.get("key","value") returns an IndexHits<Node> that you can iterate
over or use getSingle() to retrieve a single matching node.

Other ways of accessing nodes in the db are getById() or traversal using the
traversal framework
or manual traversal starting from the reference node (gDB.getReferenceNode())
that you should connect your graph to.
Cheers
Michael
