Abstract
An improved search engine technique allows a user to ensure that an untrusted search engine provides complete and correct search results without requiring large proofs for large data collections. Thus techniques are presented for a trusted crawler to index a distributed collection of documents and create an authenticated search structure that allows an untrusted search server to return reliably complete and correct search results.
