Expanding Search / Similar Topic Externally

All wise and all-knowing Discourse Community!

Hope everyone is well. My first Topic on the Community w00t!

We have been leveraging Discourse [hosted, SaaS] for almost and year and really happy. Though we want to start cross-pollinating our Docs/Knowledge Base/Community together. From our Docs and KB side, we could potentially hit the Discourse Search API.

From Discourse, user experience, goal we have is to enable the Search and potentially the Similar Topic feature to search our Docs/KB APIs.

Not sure if anyone has taken this on before and any ideas on where to get started would be sweet. One avenue would be building a plug-in and merging the results.

Thanks for any pointers!
