    Topsy expert search uses keyword mentioned in tweets to find experts. It is very effective for specific terms and longer tail concepts eg: “lucene”, “solr”, “real-time search”, “speech recognition”. It is less effective on abstract concepts like “movies” or “seo” that people talk about without mentioning literally in their tweets.

    We are working on including several signals from outside the tweet text to provide more rewarding results overall. Some of these signals are specifically aimed at performance on conceptual queries.

    As for username search, we see it as a different use case — username search is about finding accounts for people you already know. Topsy expert search is about finding accounts for people who specialize or have expertise in a subject.

    Thanks for the feedback and the mention.

    Vipul – thx for the clarification, and you’re right that there’s a different use case in the username search tools that I mentioned. I think what you’re trying here would be a great tool, but it needs to be better. I hope it continues to improve, and please do keep us posted on any new developments.

    Matt, we pushed out a change to the expert ranking algorithm this morning that makes results more robust on the same data set. We’ll keep you posted as we update Expert Search in the future.
