In this talk, we'll walk through a real migration from PostgreSQL's pg_trgm to Elasticsearch — driven by growing latency and database pressure. We'll cover how to preserve trigram-like behaviour using n-grams, prefixes, keywords, and shingles, how to validate the new system with real queries and synthetic typo cases, and the production details that made the migration safe: replication, checkpointing, lag handling, and replayable indexing. A practical talk for anyone dealing with fuzzy search at scale — or planning a migration where quality, performance, and reliability all matter. Talk #2 details TBC soon
