* A query thunk is the function responsible for sending the query to MongoDB,
|
||
|
|
* like `Query#_findOne()` or `Query#_execUpdate()`. The `Query#exec()` function
|
||
|
|
* calls a thunk. The term "thunk" here is the traditional Node.js definition:
|
||
|
|
* a function that takes exactly 1 parameter, a callback.
|
||
|
|
*
|
||
|
|
* This function defines common behavior for all query thunks.
