How to make this keyword search work?

I am trying to create keyword search for my meteor webapp. And For the most part it works the problem is it is very slow. In the current form when making a article the user gives it keywords. keyS queries one article with a keyword from the search array(skeywords) at a time from mongodb then gives it a score and the 100 highest scored articles are sent to the user. How could it query all the relevant articles at once?

ps Am I going about this all wrong.

The data coming from the client looks like this.

var keyw = ['java','code','jdk','food','good','cook'];
Meteor.call('keyS',keyw);

the data coming out of 'keyS' looks is a array of article ids.

example

Sarticles = [someid,someid]

server

Meteor.methods({
    keyS: function(skeywords) {
        article: 'tempid',
            var score = {
        totalScore: 0
        };
        var potentials = [];
        var badArticles = [];
        var i = 0;
        while (i < skeywords.length) {
            var key = [];
            key.push(skeywords[i]);
            console.log(key);
            if (typeof badarticles == "undefined") {
                var theArticle = Articles.findOne({
                    articlekeywords: {
                        $in: key
                    }
                });
            } else {
                var theArticle = Articles.findOne({
                    $and: [{
                        articlekeywords: {
                            $in: key
                        }
                    }, {
                        _id: {
                            $nin: badArticles
                        }
                    }]
                });
            };
            if (typeof theArticle == "undefined") {
                console.log("no more articles with that keyword")
                i++;
                continue
            }
            score.post = theArticle._id;
            console.log(score.article);
            score.totalScore = 0;
            var points = 0;
            var theKeywords = thearticle.keywords;
            console.log("score worked");
            var points = 0;
            for (var a = 0; a < skeywords.length; a++) {
                var keynumber = theKeywords.indexOf(skeywords[a]);
                if (keynumber > -1) {
                    points++
                } else {
                    continue
                }

            };


            score.totalScore = points;
            console.log(score.totalScore);
            if (score.totalScore > 2) {

                var ID = score.article;
                badposts.push(score.article);
                console.log("added to potential" + ID + "to bad");
            } else {
