setting start param in ft_search doesn't appear to change search results

[ghost]

Hi @sckott,
I have been trying to use ft_search to extract articles in batches so I limit searches to 2000 as anything greater than this is too slow (i.e. > 20 min) and results in the following error

Error: parse error: premature EOF (right here) ------^ 

so I have tried using the start param in ft_search, but if I start at 10 or 2000 it doesn't make a differences (i.e. always seems to start from zero).

here is an example:

 res_1 <- ft_search(query = 'ecology', from = 'scopus', 
                    scopusopts = list(
                      key = Sys.getenv('ELSEVIER_SCOPUS_KEY'),
                      facets = "subjarea(count=100)"
                    ), limit = 10)



> head(res_1$scopus$data$`dc:title`)

[6] "Creativity: linchpin in the quest for a viable theory of cultural evolution"        

res_2 <- ft_search(query = 'ecology', from = 'scopus', 
                   scopusopts = list(
                     key = Sys.getenv('ELSEVIER_SCOPUS_KEY'),
                     facets = "subjarea(count=100)"
                   ), limit = 10, start = 10)
