My experience so far with companies that operate in this manner, has been something like: 1) Community member asks question. 2A) Answer is already in documentation, which can be easily linked to. Or 2B) Can be answered in-line, with an action item to add clarification/more details to the docs. This feels like a pretty scalable solution for the most part. If there are still recurring questions you might want to look at the discoverability/layout of your docs, but usually I've found that other community members start linking each other to docs if the same question comes up again and again.
