Das ist aber auch nicht die feine englische Art: der Technikchef von #elasticsearch stellt einen #Exploit für eine Sicherheitslücke der Konkurrenz von #mongodb auf GitHub und gefährdet damit massiv die betroffenen Instanzen und Nutzer.

Kết hợp cả BM25 và semantic (hybrid) mang lại tốc độ + độ chính xác tối ưu. Nên triển khai pipeline ELSER, tạo trường sparse_vector và dùng bool‑should. #Nextjs #VectorSearch #Elasticsearch #SemanticSearch #BM25 #AI #CôngNghệ #SearchEngine #TìmKiếm

Postgres is everywhere. Millions of developers use it and love it. It's the database behind Stripe, Instagram, Spotify, and countless startups. Search is everywhere too. Every app needs it. Product catalogs. Documentation. User content. Support tickets. And now: AI agents and RAG pipelines that need to find the right documents before generating answers.
