get_metadata(urls, fields = c("id", "url", "naked_titre"),
  sleep_time = 0.05, step = 500,
  backend = "http://147.94.102.65:8983/solr/documents/select")

`urls`	a vector of urls
`fields`	the fields to get (vector)
`sleep_time`	how long (in seconds) the function should wait before two API calls. Be gentle to the backend!
`step`	how many values should be sent to the API at once (an integer). Advised value is 500; choosing a higher value may lead to getting errors 400.
`backend`	the solr backend
