Sharepoint Not show search result when page load

Question

I have Sharepoint 2013 and Employee Directory. Search page whit 2 webparts (search input field and search results). Querytext: "{searchBoxQuery}*" to search for parts of words. How to set to not show result until the user not presses enter or the search button?

Answer 1

Use the question mark (?) operator - this means that if the variables inside this statement are blank or empty then everything between {? and the matching end brace } will be omitted from the expanded query.

e.g. {?searchBoxQuery}*
