title: Executing multiple Mongoose queries
body: <p>I'm using node and mongoose to run queries against my mongodb. I have a set of 3 queries that I'm running as follows : </p>
  
  <pre><code>company.find({ 'shortName': eval("/" + req.params.query + "/i"), logoFileName : {$exists : true} }, function(err, b){
          if(err){
              console.log('brand query not found! ' + err);
              res.send(500, "Something broke!")
          }
          else{
              console.log("length of b : " + b.length)
              if(b.length&gt;1){
                  res.render('index', {
                      potentialBrands : b
                  })
              }
              else{
                  var brandResults  = b[0];   
  
  
              var industryQuery = company.find({GICSIndName: eval("'"+brandResults.GICSIndName+"'")}).sort({marketCap: -1}).limit(10);
  
              industryQuery.exec(function(err, industry){
                  if(err){
                      console.log("There was an error! : " + err)
                      res.send(500, "Something broke!")
                  }
                  //if the colors have yet to be defined
                  if(typeof brandResults.associatedColors[0] !== 'undefined'){
                      var colorQuery = company.find({'associatedColors.colorFamily': eval("'" + brandResults.associatedColors[0].colorFamily + "'") });
  
                      colorQuery.exec(function(err, colors){
                          if(err){
                              console.log("There was an error! : " + err)
                              res.send(500, "Something broke!")
                          }
                          console.log(colors);
                          res.render('brand',{
                              brandResult : brandResults,
                              industryResult: industry,
                              colorResult: colors,
                              queryName : req.params.query
                          });
                      })
                  }
                  else{
                      res.send(500, "Something broke!")
                  }
              })
  </code></pre>
  
  <p>My current structure seems rather inefficient and I was wondering if there is something within mongo or mongoose that is built for handling such queries. </p>
