Show the record details if search return 1 record only in Pawtucket2

When the search returns only 1 record, Pawtucket2 will show the detail page of the record instead of the MultiSearch/Index?search=xxx page.

May I know how to change it to always show the search result instead of showing the record detail directly?

In search.conf add this:
dont_redirect_to_single_search_result = 1

Thanks jeffschneider.

It is working on Pawtucket2, but not work on Providence. But thanks for your information.
