This function sends a query to the Web Of Science Starter API (https://developer.clarivate.com/apis/wos-starter) and returns references that match this query.
To learn how to write a WOS query, users can read the WOS documentation available at: https://images.webofknowledge.com/images/help/WOK/contents.html. A list of WOS field tags is available at: https://images.webofknowledge.com/images/help/WOS/hs_wos_fieldtags.html.
It's strongly recommended to use the function wos_search before to have an idea on how many records you will download.
wos_get_records(query, database = "WOS", limit = NULL, sleep = 1)a character of length 1. The query to send to the WOS Starter
