I am trying to analyze the article bibliography using Scopus API.

When I run scopus_search(), I seem to run into an error due to 5,000 limit API, so I change the start and max_count argument but it is not working.

rt_query <- scopus_search(query = "TITLE-ABS-KEY(Radiotherapy) AND PUBYEAR = 2022",
                          view = 'COMPLETE',
                          start = 5001,
                          max_count = 10000,
                          headers = insttoken)

Error in get_results(query, start = init_start, count = count, verbose = verbose,  : 
  Bad Request (HTTP 400).

The weird thing is that the limitation only strikes when I try to fetch information that starts after the 5000 response.

Any idea on how to resolve this?
