I am trying to sort the data in al alphabectival order but the results keep changing everytime I run the query.

Not sure if that some something to with aggregation or what is going one. Here is my query

db.getCollection(“reportings”).aggregate

([

{

$match: {

createdAt: {

$gte: ISODate(“2022-05-01T22:58:18.987+0000”),

$lte: ISODate(“2022-05-13T22:58:18.987+0000”)

},

```
},
},
