Search CORE articles

core_articles_search(
  query,
  metadata = TRUE,
  fulltext = FALSE,
  citations = FALSE,
  similar = FALSE,
  duplicate = FALSE,
  urls = FALSE,
  faithfulMetadata = FALSE,
  page = 1,
  limit = 10,
  key = NULL,
  parse = TRUE,
  ...
)

core_articles_search_(
  query,
  metadata = TRUE,
  fulltext = FALSE,
  citations = FALSE,
  similar = FALSE,
  duplicate = FALSE,
  urls = FALSE,
  faithfulMetadata = FALSE,
  page = 1,
  limit = 10,
  key = NULL,
  ...
)

`query`	(character) query string, required
`metadata`	(logical) Whether to retrieve the full article metadata or only the ID. Default: `TRUE`
`fulltext`	(logical) Whether to retrieve full text of the article. Default: `FALSE`
`citations`	(logical) Whether to retrieve citations found in the article. Default: `FALSE`
`similar`	(logical) Whether to retrieve a list of similar articles. Default: `FALSE`. Because the similar articles are calculated on demand, setting this parameter to true might slightly slow down the response time
`duplicate`	(logical) Whether to retrieve a list of CORE IDs of different versions of the article. Default: `FALSE`
`urls`	(logical) Whether to retrieve a list of URLs from which the article can be downloaded. This can include links to PDFs as well as HTML pages. Default: `FALSE`
`faithfulMetadata`	(logical) Returns the records raw XML metadata from the original repository. Default: `FALSE`
`page`	(character) page number (default: 1), optional
`limit`	(character) records to return (default: 10, minimum: 10, maximum: 100), optional
`key`	A CORE API key. Get one at https://core.ac.uk/api-keys/register. Once you have the key, you can pass it into this parameter, or as a much better option, store your key as an environment variable with the name `CORE_KEY` or an R option as `core_key`. See `?Startup` for how to work with env vars and R options
`parse`	(logical) Whether to parse to list (`FALSE`) or data.frame (`TRUE`). Default: `TRUE`
`...`	Curl options passed to `HttpClient`

core_articles_search does the HTTP request and parses, while core_articles_search_ just does the HTTP request, gives back JSON as a character string
