I am a senior Electrical and Computer Engineering student at the Aristotle University of Thessaloniki (Greece) interested in wireless communications, IoT, AI, cloud technologies, and biomedical engineering. ![]() Hi, I am Foteini Savvidou, a Microsoft Learn Student Ambassador and Microsoft MVP from Greece! Vector search works by transforming data, such as text, images, videos, and audio, into a numerical representation that is called vector embedding and applying nearest neighbor algorithms to find similar data. This method is also known as "reverse image search." In a vector search system, you can simply use the image of a product to find similar ones instead of struggling to come up with the proper search words. Consider the second scenario from the paragraph above as an example. Unlike traditional search systems that rely on mentions of keywords, tags, or other metadata, vector search leverages machine learning to capture the meaning of data, allowing you to search by what you mean. Have you ever found yourself in a situation where you remember what happened in a movie but struggle to recall its name and can’t come up with the right words to search for it? Or, maybe you’ve had that moment when you have a picture of a product you wish to purchase but aren't sure how to find it online.
