Abstract
Examples of the present disclosure describe systems and methods for enhancing the privacy of a personal search index. In some aspects, a personal cleartext document may be used to generate an encrypted document digest and an encrypted document on a first device. A second device may decrypt the document digest, build a personal search index based on the decrypted document digest, and store the encrypted document in a data store. The first device may subsequently receive a cleartext search query that is used to query the personal search index on the second device for encrypted documents.
