Search doesn't work.

The 'GET /job/search?q=' request always returns a empty array, no matter what I put in. All other requests are working fine.

This is my program:

`var kue = require('kue')
var queue = kue.createQueue();

for (i = 0; i < 500; i++) {
var job = queue.create('email', {
title: 'i:' + i
, to: 'tj@learnboost.com'
, template: 'welcome-email'
}).searchKeys( ['to', 'title'] ).save()
.save( function(err){
if( !err ) console.log( job.id );
});
}

kue.app.listen(...[config here]...);
console.log("Running on http://127.0.0.1:" + argv.p);`

Thanks,
Alex

Reproduce the GET /job/search?q= request with the provided Kue program and inspect the route and the searchKeys/save flow it exercises. Compare the indexed keys with the query behavior; done means searches return the created jobs for both “to” and “title” values, with the existing requests still working.
