Regarding the search feature:
There are two search tools built into this board. One is to the left, next to 'HOME' (below your avatar), and it works pretty well. I just searched for "Cannot load /usr/lib/httpd/modules/libphp5.so" and the link above came up as the first result.
The other search tool is to the right and has 'Now powered by KnowledgeDex' below it. It tends to break once or twice a year and takes a bit of time before it gets fixed. Right now it's broken but I recall bigpaws saying the problem has been reported.
The other search option does work pretty well, i hadnt tried it before, assuming that both were linked.
A simple interim workaround would be to have the text input box (not working courtesy of knowledge dex) linked to the search function that actually does work.
