+ * JSON data can be queried in a variety of ways:
+ * 
+ * 1. Simple:            `first()`, `last()` and `nth()`
+ * 2. Postgres style:    `->`, `->>` and `#>`
+ * 3. JSONPath style:    `$..`, `$.store.book[*].author`, `$..book[?(@.price<10)]` (etc)
  * 
  * Note: The extraction techniques employed here are simple key / value comparisons. They do not use any native JSON
