You definitely will not see all three q values when you pass the query in the manner you are trying, because you are making a JavaScript object there and yes, there will only be one q value:

$ node

> {q:'help',q:'moreHelp',q:'evenMoreHelp'}

{ q: 'evenMoreHelp' }

Superagent allows query strings, as in this example straight from the docs:

request

  .get('/querystring')

  .query('search=Manny&range=1..5')

  .end(function(res){



  });

So if you pass the string 'q=help&q=moreHelp&q=evenMoreHelp' you should be okay. Something like:

req.get('website.com').query('q=help&q=moreHelp&q=evenMoreHelp').end(...)

If this is too ugly, you can try (WARNING: I have not tried this):

req.get('website.com')

 .query({ q: 'help' })

 .query({ q: 'moreHelp' })

 .query({ q: 'evenMoreHelp' })

 .end(...);
