Datediff in Criteria operator in spring-data-mongodb not working - spring

Question

Can I have difference between two dates to greater than 0 in Criteria operator in spring-data-mongodb? I wrote the query below :
Criteria c= Criteria.where("myDate").gte(startDate).
andOperator(Criteria.where("myDate").lte(endDate).andOperator(Criteria.where("studentId").is(studentId).andOperator(Criteria.where("currDate - myDate").gt(0))));
This query not working.
If possible please help me in getting this query work with spring-data-mongodb.
Edit:
The mongodb pipeline query is as follows:
{ "aggregate" : "__collection__" , "pipeline" : [ { "$match" : { "myDate" : { "$gte" : { "$date" : "2000-01-01T07:57:33.231Z"}} , "$and" : [ { "myDate" : { "$lte" : { "$date" : "2015-11-05T07:57:33.231Z"}} , "$and" : [ { "studentId" : "100" , "$and" : [ { "currDate - myDate" : { "$gt" : 0}}]}]}]}} , { "$project" : { "status" : 1}} , { "$group" : { "_id" : { "status" : "$status"} , "activeCount" : { "$sum" : 1}}}]}

For it to work, you'd essentially want to convert the current aggregation pipeline to this:
var pipeline = [
{
"$project" : {
"status" : 1,
"studentId" : 1,
"myDate" : 1,
"dateDifference": { "$subtract": [ new Date(), "$myDate" ] }
}
},
{
"$match" : {
"studentId": "100" ,
"myDate": {
"$gte": ISODate("2000-01-01T07:57:33.231Z"),
"$lte": ISODate("2015-11-05T07:57:33.231Z")
},
"dateDifference": { "$gt" : 0 }
}
},
{
"$group": {
"_id": "$status",
"activeCount": { "$sum" : 1 }
}
}
];
db.collection.aggregate(pipeline);
The Spring Data MongoDB equivalent follows:
Criteria dateCriteria = new Criteria().andOperator(Criteria.where("myDate").gte(startDate).lte(endDate),
Criteria.where("dateDifference").gt(0));
Aggregation agg = Aggregation.newAggregation(
project("id", "status", "studentId", "myDate")
.andExpression("currDate - myDate").as("dateDifference"),
//.and(currDate).minus("myDate").as("dateDifference"), <-- or use expressions
match(Criteria.where("studentId").is("100").andOperator(dateCriteria)),
group("status"),
.count().as("activeCount")
);
