Sure I'm missing something, but

Basically this is a first pass at incorporating an embedded instance of ES
for testing. We'd then possibly even bundle up ES for deployment using
something similar. However, it's not working. I'm sure there's something
fundamental I'm missing, I just can't see it :S

Here is the fixed one. Two things: ElasticSearch is near real time search
engine, so, either you wait for a second till the indexing is visible, or
you can call refresh. I have changed it to call refresh. Second, the get
returns a GetField, and you get a list of values. Here it is:

Nice! Wasn't sure if when you did an actionGet on an IndexResponse it waited
until it was actually indexed or not.

Thanks.
