How is Splunk Answers both as a forum and wiki/content repository setup including search built and powered? Is it powered and indexed via splunk ?
Splunk wiki is powered by - https://www.mediawiki.org/wiki/MediaWiki
that should take care of the search part as well.
Splunk Answers, as per my understanding, it is splunk's own portal. (not sure, but maybe, built with tools like php/javascript/python, etc). search also splunk takes care of(after all, splunk is a searching company;))
