Course.find(
 
 instTypeId: 1,

You can use Object.assign to add values to the search object if they exist:

let instId;
let majorId = 1;

if (instId)
 search = Object.assign(search, "institute.instId": instId);

if (majorId)
 search = Object.assign(search, "institute.majorId": majorId);


Course.find(search , (err, foundCourses) => 
 // Do stuff
);

You can build query object in similar fashion:

var query = 
if (req.body.instId) 
 // using object destructuring
 query = ..., "institute.instId": req.body.instId 

However, it is advisable to set up some validation depending on use case

let search = 
 instTypeId: 1,

;
if (req.body.instId) 
 search["institute.instId"] = req.body.instId;

if (req.body.majorId) 
 search["institute.majorId"] = req.body.majorId;

Course.find(search)
