WEIRD: index name seems MATTER... different behaviors when you name it differently!

[Ranqi Zhu]

Version 1:

build index like this:

Index<Vertex> indexName = ((IndexableGraph)m_dbg).createIndex("name", Vertex.class);
indexName.put("name", name, v);

get index like this
Index<Vertex> index = ((IndexableGraph)m_dbg).getIndex("name",Vertex.class);
Vertex from =  index.get("name", name).iterator().next();

This code works, but problem is the index's name is "name", and under orientdb's console, when you query on V, it does not use it at all.Query is still slow.

It seems the system expect "V.name" instead.

so

Version 2:

build index like this:

Index<Vertex> indexName = ((IndexableGraph)m_dbg).createIndex("V.name", Vertex.class);
indexName.put("name", name, v);

get index like this
Index<Vertex> index = ((IndexableGraph)m_dbg).getIndex("V.name",Vertex.class);
Vertex from =  index.get("name", name).iterator().next();

In this case, index created is "V.name", under oriendb console, query on V is much faster, apparently system recognizs the index.

Howeever weird thing is: index.get("name", name) return empty.

I also tried

Index<Vertex> indexName = ((IndexableGraph)m_dbg).createIndex("V.name", Vertex.class);
indexName.put("V.name", name, v);

get index like this
Index<Vertex> index = ((IndexableGraph)m_dbg).getIndex("V.name",Vertex.class);
Vertex from =  index.get("V.name", name).iterator().next();

index.get still returns empty... query in console is fast.

In this case, the only different thing comparing to version 1 is, "name" becomes "V.name".
