how to search in front end if your DB for existing input name and if there is one that matches the inputs value, show an alert

Do a search for things, who’s name is the input’s value, then check the count of the returned list…

If it’s 0 then the input name is unique… if it’s more than 0 then it’s not, so show an alert.
