Serch properties inside the site

Actually I didn't understand...
What's your problem?
Every word of your query string must be longer than 3 chars (4 or more)

you can use the contact form.
however, I understood what you're saying.
You're customer is looking for "814" and he doesn't find anything.
That's because the search string must be 4 chars or longer. I can't do anything since it's a server settings

Did you enabled the fulltext search in the backend?
Did you rebuilt the properties/customers keys?
Please email me the access as super admin, so I can take a closer look
