We are currently serving queries on Topsy.com, Otter API, Topsy Analytics & Topsy Social Modules from a 3-week deep index, while we rebuild our larger index to bring you new features and faster results.  Our full index will come online before March 21st.  Till then our fresh index will serve all queries and will continue to update in real-time. 

This operation will have no impact on the Topsy button, trackback pages and fresh results.  However, expert search will return fewer results and all time window will be essentially the same as 1-month window.  

If you have any questions, write to us at support@topsy.com and we'd be happy to answer them.
