node.js - $all mongodb node js -

-

i implementing search keywords mongodb , node js, see there operator $all in mongo selects documents field holds array , contains elements.

here source code node js

exports.find = function(req, res) {     var b=req.params.search;     var query = {};     var cadsrch = b.split(' ');     var l = cadsrch.length;     var = 0;     (i = 0; < l; i++) {         if(cadsrch[i]!=''){           query[i]=new regexp('^'+cadsrch[i], 'i');         }     }      db.collection('publicacion', function(err, collection) {         collection.find({tags: {'$all':query}},{title:true,content:true}).limit(5).toarray(function(err, items) {             res.jsonp(items);         });     }); };

the above source not work, query works in mongo->

db.publication.find({tags:{$all:['chevrolet','car']}})

and strange '$in' instead '$all' works, useful work '$all' implement exact searches

you have defined query object {}. however, example use in mongo shell has array [].

i know "kind of" same thing, it's worth making these same type.
