Literature search
Type a query the way you would say it — an author, a few words of the title, a topic, a year or a range. The right query is built for each database and the results appear below, on this page.
Also open this query in
Try: Lisi Marrone modular symmetry 2023-2025 · neutrinoless double beta decay since 2022 · T2K oscillation last 2 years · Feruglio modular forms flavour
How it works
The query you type is parsed in your browser into structured fields — author,
title, topic, collaboration, date range — which are shown as chips so you can see
exactly how the sentence was understood, and corrected by hand if the guess was
wrong. Each database then receives a query in its own syntax: INSPIRE's
a Lisi and t "modular" and de 2023->2025, Crossref's query.author with
from-pub-date filters, OpenAlex's filter= expressions.
Everything happens in your browser. This site runs no server-side code, so the
requests go directly from you to the databases: nothing you type is sent to,
logged by, or stored on global-nu.org.
How arXiv is reached. A browser may read a remote API only if that API sends
the appropriate CORS header, and export.arxiv.org does not — a direct call
from this page would be refused by the browser before you saw anything. But
arXiv registers a DOI for every preprint with DataCite, under the
10.48550/arXiv.* prefix, and DataCite's API does send CORS and needs no key.
So the arXiv results here are arXiv's own metadata, deposited by arXiv, fetched
from the one place a browser is allowed to read it.
Why not NASA ADS. Its search API is public and documented, but it requires a personal token, which would have to be published in the page source to work — so for ADS the parsed query is turned into a correct search URL and offered as a button instead.
Results are capped at 20 per database, and every outbound link opens in a new tab, so you never lose your place here.
