With the rise of AI, all e-commerce shops should get a great faceted search, augmented with a great semantic search.
e-commerce shops need both, as facets are the standard for navigating among product attributes, while semantic search prevents most empty results due to keywords mismatch.
There a plenty of technologies, APIs, or plugins for search and Question Answering.
But most are 100% classic, or 100% AI, or require a heavy integration, or lack open source choices.
