Advanced search for your legacy application
summary
Live-codes an integration that adds full-text, geo and aggregation search to a legacy RestX / Hibernate app without changing existing SQL or dev workflow. Uses MySQL + Hibernate + RestX as the source, indexes into Elasticsearch 6 + Docker Compose via the Java high‑level client and Jackson, solves slow per-document writes with a bulk processor, demonstrates pagination, multi‑match, analyzers, autocomplete and dashboards and loads 1,000,000 documents — the demo ends responsive after fixing flush and bulk settings.
