Domain name in search results?

Hi there.

I must say, i really like this plugin!!
One small problem is coming up: When i search for “Klebenagel” all Products are shown in search results. It is possible that this happens cause the domain has this word in the url (klebenagel.shop), and if yes, is there a solution to fix this?

Thank you very much in advance!
