Mongoose delete multiple data at once

Question

I have a big list of ids that I want to delete from mongodb from multiple models, the main idea is that I have the same id for a document in multiple schemas and I would like to delete a document from each model. I am doing it like this:

_.each(wrongList, function(item) {
        UPUSTP.find({id: item.id}).remove(function(err) {
            if (err)
                console.log("Error while deleting " + err.message);
        })

        UPUANAM.find({id: item.id}).remove(function(err) {
            if (err)
                console.log("Error while deleting " + err.message);
        })

        UPUEXE.find({id: item.id}).remove(function(err) {
            if (err)
                console.log("Error while deleting " + err.message);
        })

        UPUEXO.find({id: item.id}).remove(function(err) {
            if (err)
                console.log("Error while deleting " + err.message);
        })

        UPUPROC.find({id: item.id}).remove(function(err) {
            if (err)
                console.log("Error while deleting " + err.message);
        })
    })

The problem is that I have 14000+ ids in the wrongList and the query works but it takes a lot of time to finish... how can I increase the time of the remove? Can I remove in batch or something like that?

I think that you could use $in operator of mongodb.

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

Something like:

UTUSTP.remove({_id: {$in: wronglist}}, function(){...}); // and so on
