In trunk(http://nightly2.sakaiproject.org:8082/portal), Search functionality is not giving results even though it has matches.
But It's working fine in 10.x(http://nightly2.sakaiproject.org:8081/portal), 2.9.3(local environment)
Attached videos can be opened in VLC player.
This is specific to the box in rwiki. If search.enable=false, then it works, but if search.enable=true then it won't work unless you also set wiki.fullsearch=false. However setting that means that results won't appear in the search tool. See the comments for the reason why.
So short answer
Default. search.enable=false, wiki.fullsearch=true = Built in wiki search works, regular search doesn't work
Setting search.enable=true, wiki.fullsearch=true = Context search in wiki doesn't work, regular search works for wiki and other tools
Setting search.enable=true, wiki.fullsearch=false = Context search in wiki works, regular search doesn't search wiki but works for other tools
