 ## Infrastructure
 
 - **Database**: PostgreSQL 15 + PostGIS 3.3 (port 25432 via Docker, DB: `gis`, user: `docker`)
-- **Search**: Elasticsearch 7.17.2 (port 9200)
+- **Search/autocomplete**: `@algolia/autocomplete-js` (frontend) against prefetch endpoints + Nominatim geocoding; no Elasticsearch integration in the app (the `elasticsearch` service in `docker-compose.yml` is a legacy remnant)
 - **Cache**: Redis (port 6379)
 - **Locale**: German (`de`), host: `luft.jetzt`

 Luft.jetzt ist eine Symfony-4-Anwendung und benötigt den üblichen LAMP-Stack mit PHP 7.1.
 
-Die Daten werden grundsätzlich in einer SQL-Datenbank gespeichert, werden aber zur Beschleunigung des Suchvorganges mit Elasticsearch indiziert; momentan ist mindestens Elasticsearch 6.3 notwendig.
+Die Daten werden in einer PostgreSQL-Datenbank mit PostGIS-Erweiterung gespeichert; Redis dient als Cache. Die Suche/Autovervollständigung im Frontend läuft über `@algolia/autocomplete-js` gegen Prefetch-Endpunkte sowie Nominatim-Geocoding — eine Elasticsearch-Integration existiert im Anwendungscode nicht.
