* This things is sorting all given modules by a JSON array.
|

|
|
* You can supply the ˋfilterˋ array with a list of filters
|
|||
|
|
* They are made up of ["metaData", "metaValue"]
|
|||
|
|
* Another argument is ˋconjunctionˋ it can be either AND or OR
|
|||
|
|
* OR means that any of the given filters should apply
|

* AND means that all filter HAVE to apply

|
|
* Current state
|

|
* This things can already handle OR requests, AND requests
|
|||
|
|
* are not supported yet. I also use the /libs/metaHandler lib,
|
|||
|
|
* at least I finnaly found a usecase for that waste of space.
|
|||
|
|
*
|
|||
|
|
* This is a small prototype which will be added into /routes/api.route.js
|
|||
|
|
* at some point. But what I was doing before was almost production testing.
|
|||
|
|
* Not good. I will need to test this further and throw some edge cases at it.
