Vector Search & RAG: The Plain English Guide to Modern AI Search

-
Image
Why You’re Probably Here You’ve probably heard terms like vector search , dot product, cosine similarity , or RAG floating around in AI conversations. Maybe you've seen them in documentation or presentations and thought, “I kind of get it, but not really.” This short guide is here to help -- using simple, practical explanations with everyday examples. No math degree required. If you’re building with AI, curious about modern search, or just want to finally understand what those terms mean, you’re in the right place. By the end of this doc, you’ll know what vectors are, how we compare them, and how those comparisons help AI give better answers using your own data. What Is a Vector (In Plain English)? A vector is just a list of numbers that represents the meaning of some text -- like a sentence, paragraph, or document. For example: “I love dogs” → [0.3, -0.1, 0.9, ..., 0.8] You don’t need to know what the numbers mean -- just that similar sentences produce similar vectors . So: “I ...

A Series of MongoPush Events

MongoPush is not only a data migration tool but also a database cluster transformation solution.  Data migration is one of many functions mongopush has. Another Bold Stroke In my tenure at Professional Services, December has been a month full of customer requested cancellations and thus resulting in many last minute engagements.  Right before the December holidays in 2020, I was assigned to an Atlas migration consultation on a short notice.  A colleague of mine already demonstrated to the customer a replica set migration to Atlas using the mongomirror tool in a previous meeting.  The customer asked me to use the same procedure and tool to mirror a 3-shard cluster to Atlas.  Unfortunately, it was not possible to migrate a sharded cluster using a simple mongomirror command.  After explaining the steps of migrating a sharded cluster using multiple modified mongomirror instances, the idea of simplifying the process of migrating sharded clusters began brewin...
