Retrieve MongoDB documents based on two fields with OR condition in Java Sprintboot application

Question

I have a MongoDB collection with two documents like

{
"field1":"value1"
}

and

{
"field1":"value2"
"field2":"value1"
}

I want to retrieve both documents in my Springboot microservice.

Query query = new Query(Criteria.where("field1").is("value1").orOperator(Criteria.where("field2").is("value1")))
List<Something> list = mongoTemplate.find(query, Something.class);

The above code returns an empty list whereas the below code returns the first document.

Query query = new Query(Criteria.where("field1").is("value1"))
List<Something> list = mongoTemplate.find(query, Something.class);

How can I retrieve both documents?

You need to use syntax such as this, i.e. like orOperator(where1, where2) instead of where1.orOperator(where2):

Criteria criteria1 = new Criteria();
        criteria1.orOperator(
                Criteria.where("dumEmployeeId").is(user.getId()),
                Criteria.where("toDumEmployeeId").is(user.getId())).
                andOperator(
                    new Criteria().orOperator(
                            Criteria.where("priority").is("Important"),
                            Criteria.where("priority").is("Urgent")
                    )
                );
