Hi @CarlosChrysalis -
With Search Full-Archive, you can request any fromDate and toDate between March 2006 and now, as long as the fromDate is earlier than the toDate.
The data is returned paginated by either 100 Tweet pages or 31 day pages, whichever is reached first from the results data. The number of matches of the rule you’re searching determines how the data is delivered:
Example:
fromDate: 2009-01-01
toDate: 2010-01-01
For a rule that has 5,000 Tweets matching in the first month (2009-12-01 to 2010-01-01), would take 50 calls to return 100 Tweets per page
For a rule that has exactly 99 or less Tweets per month, it would take 12 calls returning available Tweets within 31 day pages:
2009-12-01 to 2010-01-01 page with 99 tweets
2009-12-01 to 2009-11-01 page with 99 tweets
2009-11-01 to 2009-10-01 page with 99 tweets
2009-10-01 to 2009-09-01 page with 99 tweets
.

2009-02-01 to 2009-01-01 page with 99 tweets
To get a preview of the number of matches for a rule, you can upgrade to the first paid tier of premium, which includes an endpoint that returns the matching count/volume histogram over the requested period.
