Natural Language Based E-Com Product or Page Search

Hello Folks,

Has anyone considered or tried using a natural language-based Product or Page content search in e-com?

e.g. search directly in the search box by typing:

1. What is the organic food for a 1-3-year-old kid?

2. How many days are allowed to return the product after receiving it?

Was it helpful and worth using?

Thanks

Roman
