Magento/EE integration - EE search not working

I have integrated EE into a Magento site, however the search functionality is not working.

Here’s what the query looks within the integration: http://mysite.com/machine-support?q=test

Here’s what the query looks like in EE prior to the integration: http://mysite.com/site/search_no_results/b1336a3d82502408772d890af2a9bd2e/

Any help is much appreciated!
