I haven't been able to get an answer/response via IRC so I will try this methodology.
When running searches at English and French Wikisources today, I have been not given search results, though it will successfully run an ajax check and locate a link, and if it is blue to forward you to that link.
These links do not give results (searches tried by myself and another)

Some assistance would be great. Regards Andrew
