Full-text search

Full-text search is like playing "I Spy" in a book or a big pile of words. You are trying to find all the things that match your search words.

Let's say you have a book about animals, and you want to find information about dolphins. If you use a full-text search tool, like the search feature on your computer or phone, you can type in "dolphin" and it will look through the entire book and find all the pages that talk about dolphins.

But it's not just looking for the word "dolphin." It's also trying to find other words that are related to dolphins, like "swim" or "ocean." The search tool knows that these words are often found near the word "dolphin," so it includes them in the results too.

Full-text search is important because it can help you find information quickly and accurately, even if you don't know exactly where to look. It's like a magic tool that reads through all the words in a book or website and finds the ones you're looking for.
