Discourse Docs plugin is not just great for Knowledge Base Topics.
This plugin also works splendidly to provide users a powerful tool for filtering and sorting through all of the Topics on a Discourse site.
While you can certainly designate and limit the Categories to provide searching across only a subset of Topics such as Knowledge Base articles, you can also think of Discourse Docs as a supplementary Search tool with an efficient “drill-down” capability…
Adding the Docs Card Filter Theme Component is also a neat way to add even more bling and functionality… (and you can further jazz up those Filter Cards with custom backgrounds and icons)…
