Search (Elasticsearch)
- Local: if ELASTIC_HOST is set (http://localhost:9200) and ES is running, the app indexes/searches with ES.
- Render: If ES is not available: indexing is safely skipped and search falls back to a simple SQL LIKE so the UI still works. No crashes.
Email (Password Reset)
- Local: set EMAIL_ENABLED=1, http://localhost:8025
- Render: set EMAIL_ENABLED=0, most real email providers require a verified account (often paid or limited free tier)
