Arguments

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
