Building Semantic Search with Transformers.js and Sentence Embeddings

# Plain-English Summary New tools now let search bars understand what users actually *mean* instead of just matching exact words—so searching "affordable laptop" would find budget computers even if that exact phrase isn't on the page. This solves a frustratingly common problem where searches come up empty because the website uses different wording than the customer does. The technology is becoming easier for companies to build into their websites without needing a team of specialists.
