Anyone who has enough data in their Confluence instance will know why I'm asking this question. I saw something that could be used for Confluence Cloud, and am (desperately!) hoping to find something that would replace the search engine in self-hosted editions.
Atlassian Team: Confluence search is bad enough that I'm starting to consider recommending we go back to MediaWiki. Finding information is, at the end of the day, far more important by far than having tie-ins to Jira and whatnot - and those tie-ins can be scripted into MediaWiki anyhow.
