Federated search
One query, merged and de-duplicated across nine academic sources - no need to search each database separately and reconcile the results yourself.
Nine sources, one result list
A single search runs against OpenAlex, Semantic Scholar, Crossref, arXiv, DBLP, CORE, DOAJ, HAL, and J-STAGE at once, and the results are merged and de-duplicated into one list - the same paper indexed by three different sources shows up once, not three times.
Automatic British/American spelling-variant expansion means "tumour" also finds "tumor," and "organise" also finds "organize" - so the same search works whether it was typed from the US, the UK, South Africa, or India.
