Need to analyze tweets on a specific topic, my application (for using Twitter API) was not approved. Instead, I tried to do it manually using Twitter Advanced Search. However it's more burdensome than using easy-to-use Twitter API, I think advanced search doesn't retrieve all the relevant tweets containing a particular keyword, as I tested it for several case.
So, there are two questions. Firstly, am I right about incompleteness of advanced search in providing results? Secondly, is there another way (or turn around) to use API without need to approval?
Specifically, is there any limit for returning results by advanced search or it provides all the possible results, just like API?
