How to find items using regex in Mongoose [duplicate]

mongoose doc for find.

mongodb doc for regex.

   var Person = mongoose.model('Person', yourSchema);
   // find each person with a name contains 'Ghost'
   Person.findOne({ "name" : { $regex: /Ghost/, $options: 'i' } },
          function (err, person) {
                 if (err) return handleError(err);
                 console.log('%s %s is a %s.', person.name.first, person.name.last, person.occupation);

   });

Note the first argument we pass to mongoose.findOne function. “{ “name” : { $regex: /Ghost/, $options: ‘i’ } }”. “name” is the field of the document you are searching. “Ghost” is the regular expression. “i” is for case insensitive match. Hope this will help you.
