Generic fielded search across arXiv preprints

Compose a boolean-AND search across any of the fielded parameters (general q, title, author, cat, and from_date/to_date submission window) and return matching papers from the arXiv.org (Cornell University) corpus. Pagination via limit (up to 2000) and offset. Sort by relevance (default), submittedDate, or lastUpdatedDate in ascending / descending order. Every paper is returned with identifiers, title, abstract, authors, categories, DOI and journal reference (when available), version number, and abstract/PDF URLs.
