Is there a way to find a specific discussion on a particular product by entering key word tags?

When I go into a particular discussion group and search for a topic, a list of discussions are displayed, but I don't want to scroll though an exaustive list of every possible topic. I simply want to enter some key words into some sort of "search" field and filter to the topic I need an answer on. Am I missing something? Please let me know.

Thanks,

Steve
