Better Search for Confluence

This add-on is simple to configure and does exactly what we need: namely, we have lots of separate workgroups using Confluence, and 98% of the time they do not want to see other groups' pages/spaces/attachments showing up in their keyword search results (and for the 2%, this add-on supports those searches as well, on the Advanced Search page). You cannot filter keyword search results in this way using native Confluence permissions unless you are willing to completely isolate workgroups from one another, so this fills an important gap for us.
