Bridgewater Associates has built Vault to let AI agents search more than 100 million documents. A central challenge is enforcing different access permissions for each email, meeting note and report.
Bridgewater Associates draws Vault's material from 135 external sources, alongside internal writing, meeting recordings and reports. Access can be restricted to specific groups or individuals.
The team found that filtering results after retrieval was fast but missed relevant material, while filtering beforehand preserved recall but was slow. It switched to Turbo Puffer native filtering, which scores only the nearest clusters containing matches.
For companies building AI agents over internal records, the example makes permissions part of search design rather than a final check. Bridgewater's infrastructure also has to serve agent swarms alongside 300 human users, with very different query volumes.
Access controls can determine the design of enterprise AI search, rather than simply being added after retrieval.
Infrastructure designed for human search may need substantial changes when AI agents become frequent users.
Bridgewater provides an implemented example, though the account does not establish whether the same approach would work equally well elsewhere.
