There are a few reasons a report will come back with 0 tweets. Of course, there might not have been any activity in the past week on that term (reports include tweets from the past 4-5 days), so if there haven't been any new tweets lately, your report will return 0 tweets. But often, there are other reasons you're seeing no tweets in your report.

First, double check that you spelled your search terms correctly. It can be easy to overlook a small error, especially in hashtags or longer queries.

Second, check the the length of your search query. Twitter search queries are limited to the length of a tweet, and long queries will break. Keep search queries under 60-80 characters to avoid errors. In addition, queries with multiple operators can be too complex, so keep your queries simple (for example, limit queries to three ORs).

Third, check the validity of your search query. Make sure you've formatted dates correctly and other specific operators are written appropriately. There's a full list of acceptable search operators here.
