Query Language
Last Updated: 2026-02-19 Confidence: High
Summary
The query interface is a single operation that encapsulates candidate retrieval, filtering, ranking, and diversity enforcement. Three primary operations: RETRIEVE (feed/browse), SEARCH (text+semantic), and SIGNAL (engagement write-back).
Key Facts:
- One query replaces what currently requires 6 systems
- RETRIEVE: feed generation, browse, related content
- SEARCH: keyword + semantic + hybrid retrieval
- SIGNAL: engagement event write-back (closes the feedback loop in the same transaction)
- All queries accept: FOR USER, USING PROFILE, FILTER, DIVERSITY, LIMIT
- Filters are composable — any combination is valid
