actually, no, here data is the parameter that is passed to your ajax
callback function (which contains the response from the server).

When you make an ajax request like that, you need to actually set the
parameters that you want to pass. Right now you're passing no
parameters, so params[:query] is nil
$.get 'search', {query: 'foo'}, (data) ->
...
would result in params[:query] being foo
and
$.get 'search', {query: $('#query').val() }, (data) ->
...
would pass the value of the field with id query (and since this code
is being called from the change event handler attached to the text
field, you can shorten that slightly to $(this).val() instead of $
('#query').val()
