 * Note: By the time of this writing (Nov 2015) all queries are taken from the query dsl
 * reference docs mirroring examples there. Here's how the queries were generated:
 *
 * <ul>
 * <li> Take a reference documentation example.
 * <li> Stick it into the createParseableQueryJson method of the respective query test.
 * <li> Manually check that what the QueryBuilder generates equals the input json ignoring default options.
 * <li> Put the manual checks into the assertQueryParsedFromJson method.
 * <li> Now copy the generated json including default options into createParseableQueryJson
 * <li> By now the roundtrip check for the json should be happy.
 * </ul>
