Well, good time for a bug report like this as I have re-worked the
search engine yesterday (to allow more flexibility and automatic
creation of keyword lists). I see the problems you describe in the old
version, but fortunately:

Clicking on htest now lists all of ctest together with several other
pages.

optimize also gives a non-empty return (though function optim misses
the keyword, I'll fix that).

optim is listed under nonlinear in the new version.

Thanks a lot for the bug report,
