Provide the ability to search comments within a single topic.
I want to search existing comments on a topic to avoid posting something if it has already been said. Manually scanning comments is too burdensome if there are many comments (>50, >75, some significant number).

Since I can't edit my post. :(
I would rather "like" an existing post that says what I like, which I think would help developers mining the data, rather than inadvertently repeat the same thing as a separate post.
