I am new to SharePoint. I am trying to add a search box to a list but I can't figure out how to do it. I have added an 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."
I am using SharePoint 2010
