ELI5: what is semantic search
// explanation
What is semantic search?
Semantic search is like having a really smart librarian who understands what you actually mean, not just the exact words you use [1]. If you ask for "how to fix a leaky faucet," it understands you want repair help, not literal information about faucets [2].
Why is it different from regular search?
Regular search just looks for your exact words, like finding "cat" when you type "cat" [1]. Semantic search is smarter—it understands that "feline" and "kitty" mean the same thing as "cat" [2][3].
What makes it work?
The computer learns the meaning of words by looking at how they're used in tons of examples, kind of like how you learned that "happy" and "joyful" mean similar things [1][5].
Why does it help you?
You get better answers because the search engine actually understands what you're looking for, not just matching words on a page [3][4].
