Advanced (elastic)search for your legacy application
summary
Starts from a Spring Boot/MySQL app and wires in Elasticsearch so repositories save the same Person entities into an Elastic Cloud index called personnes using Jackson and Spring Data, demonstrating index creation, mappings and custom analyzers to fix tokenization and partial matches. Shows near realtime problems and fixes with a bulk processor and refresh delay, implements delete sync and multi-field multi_match queries, adjusts scoring and sorting, and runs the live demo end to end proving the integration works without rewriting the app.
