I have an issue with the Twitter Merging feed. When I try to import results for a subject that has over 1500 tweets per day (min time period in Omniscope), the results are not available - not even the first 1500 tweets on that subject. Is there a way around it?
I think the problem here is that your trying to search for data and your specifying a date such as "On 1st May 2012". Unfortunately the Twitter search API only goes back a few days/weeks at the moment. We are hopeful they will change this in the future, but in the meantime we've added some help text in the Twitter block panel.
If you need to keep track of Twitter statistics over a longer time period you could setup an Omniscope workflow to generate these statistics and schedule it to run every day.
