Answer 1

If you are doing this in Java you could select the name of the buyer like this:
$..[?(#.purchased && #..name contains 'abc' && #..name contains 'def' )].name
In JavaScript, you can use this a query like this:
$.[?(#.purchased && #.purchased.some(e => e.name==='abc') && #.purchased.some(e => e.name==='def') )].name
Both queries use a similar approach:
We filter for a purchased-property, then use a function to search the keys in the map for certain values
Jayway's JsonPath offers a contains function to do so;
In JavaScript we leverage script evaluation to search the map/dict for our key/values
So, the .some() is not a JsonPath function but some modern JavaScript (:D).
This is kind of a workaround in both cases but it gets the job done.
You can test both online here. Select the tab JayWay and click Go for the first query, switch to tab Goessner to run the JavaScript sample (you can run the second here as well).
