Hi Gustavo and Junxiong
There is no other setup required. Exploratory is simply throwing a query against Twitter with your search keyword and Twitter returns results based on your Twitter account status (standard, premium or enterprise). So we get what Twitter returned. What we can do here is use supported filter condition by Twitter.
For example, If you need older tweets, you can use the
until condition like below.
if you want to get tweets related to dplyr until 2019-01-25
You can query it by
dplyr unit:2019-01-25 as a Search Text.
you can also use
since condition so if you want to get tweets between some time range, you can do as follows:
dplyr since:2019-01-27 until:2019-01-30
Again, one thing we need to be aware of is that if your Twitter Account is "standard" there is some limitation (which is imposed by Twitter)
The Twitter's standard search API (search/tweets) allows simple queries against the indices of recent or popular Tweets and behaves similarly to, but not exactly like the Search UI feature available in Twitter mobile or web clients. The Twitter Search API searches against a sampling of recent Tweets published in the past 7 days.
Before digging in, it’s important to know that the standard search API is focused on relevance and not completeness. This means that some Tweets and users may be missing from search results. If you want to match for completeness you should consider the premium or enterprise search APIs.
