Query Database in situation of both [and] and [or] together

[Mark Wong]

How do I query the database with something like
code{"$or": [{"and":[{"user_name": "..."},{"Receive":"..."}]},{"and":[{"user_name":"..."},{"Receive": "..."}]}]}/code
Because I need to find the target which contains for example [user_name: abc + Receive: xyz] or [username: xyz + Receive abc] at the same time
when I use the code above, it only returns
code[

]/code
