Ever wondered how a computer knows that two sentences mean almost the same thing? 🤔

“I'm feeling sleepy.”
“I'm really tired.”

Different words. Similar meaning.

That’s where Similarity Search comes in. Text can be converted into embeddings (vectors), and similar meanings are represented closer together in vector space.

So instead of searching only for the exact same words, we can find results with a similar meaning.

This is used in search engines, chatbots, recommendation systems, document search, RAG, and much more.
