mognoose searching with regular expression in multiple columns

Question

I have a mongoose model with schema defined as -

var campusNotesSchema = mongoose.Schema({
    noteId:{type:String, unique:true, default: uuid.v4()},
    ti         


        

Answer 1

You can user $or operator in mongoose to return results with either of matches
$or http://docs.mongodb.org/manual/reference/operator/query/or/

Campusnotes.find({'$or':[{title:new RegExp(searchText,'i')},{description:new RegExp(searchText,'i')}]}).exec(function(err, collection) {
    res.send(collection);
})

To search in array for matching strings, you need to use $in operator of mongo:

$in : http://docs.mongodb.org/manual/reference/operator/query/in/

Answer 2

use this query ,$option = i, will skip the lower /upper case when you are inserting data into TAG array first make it lowercase and search with lowercase this would be easy.

Campusnotes.find({title:{'$regex':searchText,'$option':'i'},description:{'$regex':searchText,'$option':'i'},tags:searchText}, function(err, collection){
res.send(collection);
});
