Retrieve. Remember. Reason - with Women of Search - Berlin - June 9 2026
2026-06-09 18:00 - 21:30 (Europe/Berlin)
An evening of search, memory & agents – brought to you by Women of Search at Berlin Buzzwords
About the Event
​Berlin Buzzwords week is our favourite time of year – and this year, we’re making it count.
​Women of Search is bringing together the community for an evening of sharp talks, honest conversations, and great company – right in the heart of Berlin (Thank you Haystack!).
​The theme? Retrieve. Remember. Reason. – three verbs that map neatly onto where our field is right now: from search and retrieval, to memory and context, to agents that actually reason and act.
​We’re thrilled to be joined by three brilliant partner communities shaping this space:
​🔍 OpenSearch – on the retrieval layer that makes everything else possible
🧠 Cognee – on memory, knowledge graphs, and what AI systems need to remember
🌾 Haystack – on orchestration, agents, and putting it all together in production
​Three short talks. Real practitioners. No fluff.
​Followed by networking, drinks, and the kind of conversations that don’t happen in conference halls.
​Who is this for?
​Women of Search started as a community for women in search – and we’re evolving. If you work in search, AI, agents, retrieval, NLP, or anything in between, this evening is for you. Women and allies warmly welcome.

Milan User Group - May 27 2026
2026-05-27 18:30 - 20:30 (Europe/Rome)
Ti è mai capitato di avere tutto sotto controllo… e comunque non capire cosa stava succedendo?
Benvenuto nel mondo moderno: microservizi, eventi, pipeline, e una valanga di dati che promettono chiarezza.
Spoiler: non basta.
Search, observability e open source condividono lo stesso obiettivo: trasformare dati grezzi in qualcosa che abbia senso, e il farlo mentre il sistema cambia, scala, e a volte …si rompe.
Non è (solo) una questione di tool. È capire come leggere, collegare e interpretare quello che abbiamo davanti.
Da qui partiamo.

Have you ever had everything under control… and still not understood what was happening?
Welcome to the modern world: microservices, events, pipelines, and an avalanche of data that promises clarity.
Spoiler: it’s not enough.
Search, observability, and open source share the same goal: transforming raw data into something that makes sense, and doing so while the system changes, scales, and sometimes… breaks.
It’s not (just) a question of tools. It’s understanding how to read, connect, and interpret what we have in front of us.
Let’s start from here.
