The documentation is a bit sparse on describing the query capabilities. Is
there a recommended online source to get familiar with Elastic Search's
syntax and terminology? Would looking into Lucene resources help?
Can you give some examples as to what you are missing? Is that how query
behave, or maybe how to construct them (using JSON for example)?

There is just the terminology hurdles which I have been able to get
over using the Lucene documentation (diff between term and field, what
is boost, etc..).
But I would appreciate an example that shows how to query an index
when presented with a JSON object, but from the Java API.
Thanks.

That should read:
"But I would appreciate an example that shows how to query an index
when presented with a JSON String, but from the Java API."
I have tried:
var source = JSON.stringify(json);
source = searchSource().query(new
QueryStringQueryBuilder(source)).buildAsBytes();
var request = searchRequest(index).types(types).source(source);
var response = getClient().search(request).actionGet();
But I get these parser exceptions:

If you have the full search request represented as JSON (with the "query"
top level element), then just pass that json (as string or bytes) to
SearchRequest#source(...).
