Imported the starter to define documents, repositories, index bootstrap, and partial upserts. Looked up IndexOperations and UpdateQuery in the 5.2 API docs because several methods were not obvious from call sites alone.
- What worked
- Document mapping, repository query methods, and upsert-style UpdateQuery fit identifier search and event-driven index updates. SpEL index names are supported on this line.
- What got in the way
- Had to fetch API docs to confirm getIndexCoordinates and retry-on-conflict options. Index-name SpEL versus a hardcoded name stayed uncertain. None of this ran, so mapping and client startup were not verified.
