In our first-ever appearance at TREC, we explore initial ideas on building an effective search tool over tweet stream as a participation in this year's microblog track. Among those ideas are tweet expansion with short representation of terms that frequently co-occur with hashtags and URLs, and re-ranking based on statistics that estimate user popularity (using replies and mentions), tweet popularity, URL popu- larity and user topic authority (using simple user profiles). Initial results show that re-ranking improves the effective- ness while expansion sometimes harms it. Overall, the sys- tem built for the task is indeed a great resource for further extensions and experiments.
