Mongo Dynamic Search Keys And Value Query

Question

How can query in Mongo DB , by the way I am using Keystone JS. I wanted to filter or get result from the Vehicle Model where keys and values from for example { 'Year' => '2019,2018', 'Make' => 'Acura,BMW' } . It will filter where year = 2019 , 2018 same with the Make.

My current code

view.on('init', function (next) {

        var q = keystone.list('Vehicle').paginate({
            page: req.query.page || 1,
            perPage: 10,
            maxPages: 10,
            filters: {
                state: 'published',

            },
        })

            .sort('-publishedDate')

        if (locals.filters.searchkeys) {

            let urlSearchParams = new URLSearchParams(locals.filters.searchkeys)


            for (var key of urlSearchParams.keys()) {

                console.log("The Key :" , key)

                //this part is where it would be dynamic
                q.where('Year').in();


            }

        }

Search Param

{ 'Year' => '2019,2018', 'Make' => 'Acura,BMW' }

Answer 1

let's say query is request params coming to backend as

let request={'Year':'2019,2018', 'Make':'Acura,BMW'}

let query={}
if(request.Year){
  let year=request.Year.split(',')         // will give array ['2019','2018']

  for(let i=0;i<year.length;i++){          //for making array of nos [2019,2018]
   year[i]=parseInt(year[i]) 
  }

  query.Year={$in:year}                       // {$in:['2019','2018']}
}
if(request.Make){
  query.Make={$in:request.Make.split(',')}     // {$in:['Acura','BMW']}
}

var Vehicle = keystone.list('Vehicle');

let q= Vehicle.model.find(query)
  .where('state', 'published')
  .populate('author')
  .sort('-publishedAt')
  .limit(5)
  .exec(function(err, posts) {
    // do something with posts
  });
