I have a field with input type search

When I try to select that with jQuery I get VM535 jquery-git.js:1529 Uncaught Error: Syntax error, unrecognized expression: unsupported pseudo: search

Check the fiddle - Fiddle

How do I select that field?
(note: I do not have any unique class or id applied to that field, actually it's plugin generated.)

Actually I am using jQuery DataTable plugin and I want to add a Go button just besides the search box. For this I am trying this workaround - to select the
search box with jQuery and add button besides it with insertAfter method. Please suggest me if there is any other way for this.
