AdminLet's chat about google separately - in the interest of staying on topic.
When I scroll through the results I see, for example, this post - where you were the reply-author, containing the word "performance" in your reply. But not anywhere else on the post. That, as a spot check, checks out.

and yes - the search finds your content in that thread (but not your part of the post) because, I suspect, your View Results is set to Topics - If instead you change it to Specific Posts (under Advanced) you will see the bits where you wrote back.
if this doesn't get us to "good enough" then post the exact URL of your search so I can look for a systemic problem.
