The document discusses pagination in MongoDB. It provides two methods for pagination: using limit() and skip(), and using sorting and querying. Limit() and skip() allow limiting the number of documents returned and skipping a number of documents to page through results. Alternatively, results can be paged by sorting on a field and forming subsequent queries based on the last result from the previous page. More advanced queries for pagination are also possible using MongoDB operators.

1. MongoDB PAGINATION
PAGINATION detailed

2. PAGINATION
Using limit() & skip()
Reference :
MongoDB(http://docs.mongodb.org/manual/reference/method/
cursor.skip/)
function printStudents(pageNumber, nPerPage) {
print("Page: " + pageNumber);
db.students.find().skip((pageNumber-
1)*nPerPage).limit(nPerPage).forEach(
function(student) { print(student.name + "<p>"); } ); }
CONS : cursor.skip() will become slower and
more CPU intensive. With larger collections,
cursor.skip() may become IO bound.

3. PAGINATION
With Query
Arrange in ascending or descending order
anish 31
manisha 29
…………
Paul 26……..
……………
…….
arjun 8
>var pageCursor = db.user.find().sort({"age":-
1}).limit(10000)
Step 2 : iterate over the cursor
while (pageCursor.hasNext()) {
paul = 26
}
Start with paul age and form the next query and
sort it again
