A search for "Thecodontia" failed.
I manually found "Thecodont", which includes the text: "... the order Thecodontia ..."
I think this should be indexed.
On en.wikipedia.org, putting "Thecodontia" into the search box and hitting enter goes directly to the article [[Thecodont]] via the redirect page [[Thecodontia]] which has existed since August 2006.
Clicking the 'search' button instead returns 10 results, including [[Thecodont]].
A failure may have been an actual failure to contact the search servers (which would show an error message), or a mis-selection of namespaces excluding the main article namespace from the search.
