Mongoose: Model1.Find, then for each result set attribute to Model2.Find, THEN render. How?

I'm trying to wrap my head around this but having some troubles.Basically, I'm first fetching "Search" objects, and then need to fetch "SearchResult" objects using SearchResult.find({searchId: search._id}, function(err, results) { ... });. I'm trying to set it up with callbacks, which for now looks something like this:function retrieveSearches() { searches = []; Search.find({}).sort('-_id').exec(function(err, searches) { if (err) { console.log(err); } callback(searches); }); } function retrieveSearchResults(searches) { search.results = []; searches.forEach(function(search) { SearchResult.find({searchId: search._id}, function(err, results) { if (err) { console.log(err); } else { search.results = results; } }); }) callback(searches); } retrieveSearches(function(searches) { retrieveSearchResults(searches, function(searchesWithResults) { res.render('profile', { title: 'Mine søk', searches: searchesWithResults }); }); }); Of course, retrieveSearchResults won't work because the callback is called before the forEach loop is done. I just don't see how I can loop through an array of objects and perform a single query on each and every one of them, use the result for something and then render.Any ideas?
