Free members are allowed two newsfeed searches each day, however the way our system is designed, it counts loading another data set as a new search. So if you do one search and then scroll down far enough to need to load another data set, that second set will count as your second search. We know it isn’t perfect, but it’s the best we can do to ensure that our restrictions are applied fairly to everyone.
If you have any other questions, let us know.
