The search command does let you search for quotes, like "uber cannon". it shows all posts with either uber or cannon in them. This would help a lot to be able to find posts so you don't start a second, or third, or ...
The problem is that Uber is so much of a common word that it's automatically ignored by the search engine. Try Google.
As an addition,one of the best rules of thumb: If there's drama, STAY OUT OF IT. Flag the post, and move on. The moderation team will deal with it. This makes things better for the community, the moderators, and the whole universe. Replying to drama just makes more drama. If you must input, send whomever a private message, but posting a drama filled reply to drama will just make you part of the problem, and that makes the drama-llama sad.
