It is not silly if you have asynchronous indexing because your content is generated by your users, one document at a time. If you want real-time indexing, that's the way to do it.

This is the default behavior for IndexTank. When an indexing call returns, whatever you indexed WILL show up in search results. We don't give you the option to commit or not commit, we simply designed IndexTank to be fast enough when indexing in real time. I'd like to see us included in that comparison as well.
