Search is one of those things that *feels* simple — until you're the one building it. Why does `$regex` fall apart at scale? How do you handle typos, relevance, and performance all at once? And what happens when users search by *meaning*, not just keywords? Join the **Dublin MongoDB User Group** for an evening dedicated entirely to **Search** — from the foundations of Apache Lucene, to building production-grade search experiences with MongoDB Atlas Search, to the frontier of Semantic Search with vector embeddings. We'll also have a real-world use case walkthrough from someone who's been in the trenches solving search problems for customers. And yes, you can walk away with an 🎖️ **Search Fundamentals Skill Badge** 🎖️ which you can share on your LinkedIn profile. No laptop needed, just your phone! *** **🛠️ What we're covering:** **The "Why" — Search is Hard** A practical look at why developers struggle with search: fuzzy matching, relevance scoring, tokenisation, and why regex just doesn't cut it. **The "Story" — A Real Use Case** Hear from a practitioner who's helped customers go from "this search is broken" to "this actually works." Less Lucene textbook, more honest problem-solving. **The "How" — Atlas Search Deep Dive** We'll go under the hood on how Atlas Search (built on Apache Lucene) works, and show you how to wire it up in your own applications. **The "Future" — Semantic Search** Beyond keywords — how vector embeddings and semantic search let your application understand what users *mean*, not just what they *type*. *** **📅 Agenda (6:00 PM – 09:00 PM)** * **6:00 – 7:00 PM \| Networking & Pizza 🍕** * **7:00 – 7:30 PM \| Search 101: How Search Actually Works** From text indexing to Lucene — the fundamentals every developer should know. * **7:30 – 8:00 PM \| Real\-World Search Use Cases** What does bad search look like? What does great search look like? Stories from the field. * **8:00 – 8:30 PM \| From Generic Search to Atlas Search & Semantic Search** How MongoDB Atlas Search brings it all together — and where vector embeddings take you next. * **8:30 – 09:00 PM \| Search Fundamentals Skill Badge 🎖️ \| Open Discussion & Networking** *** See you there! 🎯

OpenClaw is having a moment. A personal AI agent that runs on your own machine, talks to you and actually gets things done. **NOTE: Registration needs to be completed here: [giveago.co/register/openclaw-1](https://giveago.co/register/openclaw-1)** It runs on your own machine - a Mac Mini, a Raspberry Pi, a VPS - and actually does things: runs commands, browses the web, manages files, talks to your apps. You reach it through WhatsApp, Telegram, or whatever chat app you already use. It works in the background, remembers context between sessions, and connects to whatever AI model you prefer. No engineering background required. If you can install an app and follow a guide, you can do this. We're running this as part of a three-event OpenClaw series this June, with this being the first. The following events build on the setup and focus on getting productive with the agent and applying it to real work use cases. **NOTE: Registration needs to be completed here: [giveago.co/register/openclaw-1](https://giveago.co/register/openclaw-1)** We'll be working through it together at Baseline, tables of people at different stages, helping each other along. Fresh install or halfway there, there's a spot for you. The goal is simple: leave with OpenClaw alive. Connected to WhatsApp or Telegram. With a personality you've written. Doing at least one real thing. What we'll work through together: * Getting OpenClaw set up (locally or hosted) * Connect to a messaging app: WhatsApp or Telegram * Picking the best model for the job * Writing a SOUL.md: giving your agent a personality that's actually yours * Setting up a MEMORY.md layer * Connecting one real skill before the day is out **NOTE: Registration needs to be completed here: [giveago.co/register/openclaw-1](https://giveago.co/register/openclaw-1)** Prep materials will be sent in advance. Come ready, or come from zero. Both are fine. Bring a laptop. That's it. Run of show: 11:00 Doors open, coffee 11:30 Intro and setup overview 12:00 Build time 13:00 Lunch 13:45 Back to building 15:30 Share what you've got running 16:00 Close **NOTE: Registration needs to be completed here: [giveago.co/register/openclaw-1](https://giveago.co/register/openclaw-1)** \-\-\- ​**Community** [Give(a)Go](https://giveago.co/?utm_source=luma) is a Dublin-based builder community running hands-on events for ambitious people who make things. 30+ events. 1,000+ attendees.

## 🤝 Host Information A co-hosted event by ProductTank Columbus & Women in Product Columbus 💡 About the Workshop AI adoption is stalling across organizations — not because of a lack of motivation or tools, but because it's fundamentally a behavior design challenge. This hands-on workshop applies proven Behavior Design models and methods to help you move from a vague organizational wish to boost AI adoption to 3-5 concrete, testable interventions you can act on starting tomorrow. Whether you're a product manager, on a product team, or just someone trying to get AI to actually stick at work, you'll leave with a clear picture of what's worth focusing on, what to ignore, and how to drive real, sustained adoption — no guesswork required. 🛠️ What to Bring Laptop: Fully charged and ready to go. AI Assistant: Have your favorite AI assistant pulled up. (Dom will be using Claude, but feel free to use whichever assistant you prefer!) 🍕 Logistics & Perks Food & Drink: Pizza and drinks provided! Parking: Plenty of free spaces available on-site. ###

Most people still use AI like a search box: type one question, get one answer, repeat. But the next step is AI agents: systems that can take a goal, break it into steps, use tools, remember context, and produce useful work for a human to review. In this beginner-friendly session, we’ll demystify what AI agents actually are — without hype or jargon. We’ll walk through practical examples of how agents can help with research, planning, writing, coding, operations, and personal productivity. We’ll cover: * What makes an AI “agent” instead of just a chatbot * How agents break tasks into steps * Where agents are genuinely useful today * Where they fail, hallucinate, or need human review * How to design simple AI workflows for your own work * A live demo of an AI agent-style workflow from start to finish No coding experience required. This is for anyone who wants to understand where AI tools are going and how to use them more effectively right now. LOGISTICS AND PARKING: The talk starts at 7:00 PM. The first half hour is reserved for everyone to get set up and mingle. Free pizza and drinks! The cheapest parking option is to find street parking, which will only cost you a few bucks. Otherwise, park in the nearby veteran's museum lot for $8. It's highly recommended you avoid the nearby $15 garage parking.
