fetch_pubmed_data::retmax

[dandycodingpipe]

There appears to be an issue when retrieving large amounts of PubMed data.

retmax = 2000 returns "Killing the request! Something is not working. Please, try again later"

Fortunately anything under still works (e.g retmax = 1500).

Thank you.

  #1) PMID retrieval from query
  query <- 'complement system AND (pathology OR pathologies)'
  my_query <- get_pubmed_ids(query)
  print(paste(my_query$Count, "PMIDs retrieved..."))
  
  #2) XML Retrieval
  sample_max <- 1000
  my_abstracts_xml <- fetch_pubmed_data(my_query, retmax = sample_max)
  all_xml <- articles_to_list(my_abstracts_xml)
  print(paste(length(all_xml), "abstracts were retrieved..."))
