Twitter is currently limiting most search results to tweets from the past 7-8 days. This varies from report to report, but most reports will include tweets that are between 6 and 8 days old.  

To be safe and ensure you get all your tweets, we recommend running reports as soon as you can after your event (please don't wait a week and assume they will still be accessible). When in doubt, run your report within 3 days of your event. And if you want longer-term tweet archiving and analysis, set up a Tracker. 

Note: When you run a free report for a term, we'll estimate how many total tweets will be in your full report (up to 1500, which is Twitter's limit on a single query). That number will be in a blue bar at the top of your free report. If you have any questions about that number or your specific query, just ask!
