I am new to SharePoint. I am trying to add a search box to a list but I can't figure uot how to do it. I have added a external content type and want to be able to search in it. So what I did was adding the WebPart: Search Box. But how to I tell the search box where to search? I thought maybe I had to set the connection but the connection menu is grayed out and telling: "The WebPart you are connecting from does not allow authoring of connections."
Can you help me?
