Vector search doesn't replace keyword search, but works alongside it to return more relevant results.
Vector search leverages the mathematical representation of text (a vector). In this process, each product and the search query are converted into vectors. The search engine then finds the products vectors that are closest to the search query vector.
The AI Search Engine then re-ranks the top 200 search results based on user behavior data including click and cart events for each search term, to show the most engaging results first.
