The rxiv APIs do not support nested search strings like Pubmed or Scopus. Therefore, flattend search strings for rxiv can become very long. Unfortunately, long search strings are not supported by Pubmed and Scopus.
Suggestion - short but dirty
[x] offer optional rxiv search string in search_runner
[x] reset query after Scopus search
maybe better (backlog)
implement distributive property for AND and OR operators
