I'm upgrading to ES 0.90 and I have some native scripts written in Java  
(currently using 0.19.8)

The _DocLookup_ in _AbstractFloatSearchScript_ (accessed through _doc()_)  
does not have the _numeric(string)_ method anymore, it was used like this:

_long myValue = doc().numeric("my\_number\_value_\*").getLongValue();\*

Now _DocLookup_ implements the _Map_ interface. So instead of  
doc().numeric("my\_number\_field"), I should do doc().get("my\_number\_field").  
Looking at the source code _get()_ returns a _ScriptDocValues_ (although  
the signature only says Object).

What should I do to get the _long_ value?

I'm gonna try:

NumericLong n = (NumericLong)doc().get("my\_number\_field");  
long v = n.getValue();

Is that the correct way of doing this?
