Recommended Site Search

Dear HB Theme,

I am wanting to have in site search on my website that will work great. As many of the customers are not expert on my products and not knowing the key words, it would be great if the search option could give similar search results, like Google does.
Not sure if that is possible in WordPress?

I am wondering if the search feature that comes on the demo will fulfill what I am looking for, or is there a WP site search plugin that you recommend such as
Relevanssi or
Search WP etc?

Thank you for your help.

David
