Issue description

I try to plugin this to my mongoose and it's working as normally but when I do with partial search such as modelOne.find({ 'comment': /hello/i }) it's not working as expected.

Steps to reproduce the issue

1. Define Model
2. Find documents that contain with text as hello in comment path
3. Check the result

Note : I use global plugin to inject req.query for this test.

What's the expected result?

• The result should count all and divided for calculate as pages
• Screenshot (2) 'pages' should be 2.

What's the actual result?

• The result is not count all and not calculate pages
• Screenshot (2) 'pages' is 1.

Additional details / screenshot

it is a good project，but it seems it can’t use "sort" function because i found the following code doesn‘t show the ideal response
”
pagination(ProductModel).find(query, null, { sort: 'price' }).page(2).size(4).display(1).exec().then((result) => {
data = JSON.parse(JSON.stringify(result));
// res.send({ records: data.records, page_num: data.display, page: page });
console.log(data);
console.log(data.records);
console.log(data.display);
});

should parseInt the params
