GLOSSARY
Embedding
A numeric representation of text, images or audio that captures meaning, letting machines find similar content by comparing vectors.
An embedding is a list of numbers representing the meaning of a piece of content, arranged so that similar things sit close together in space. 'How do I reset my password?' and 'I can't log into my account' produce nearby vectors even though they share almost no words.
This is the engine behind semantic search and RAG: documents are embedded once, queries are embedded at ask-time, and the closest matches get retrieved. It is why modern tools find the right passage even when your wording differs completely from the source.
