Each new tweet push all the first tweets to new rows. And the new tweets harvested are written in the first rows of the sheet.
This is how the script already works 🙂
Is it possible to store the tweets from the 2nd line to n-line, and if there are new ones, to keep been written from the n-line to m-line?

If there is a tweet in row 2 of Archive then send id to Twitter with search term else just send search term. If there are n tweets in the result insert n rows into Archive from row 2 and add new data
