How to search document from only one document library in SharePoint 2013.

Edit: You could also use the ListId managed property which is auto-populated. You can get the list GUID for the document library by going to the document library settings page and getting the id from the URL (it looks like something like feff2548-dd30-4372-80d1-c20a1a14b710) then your query would be ListId:feff2548-dd30-4372-80d1-c20a1a14b710

you could define a custom result source (search scope) to limit queries to this library and then have a custom page to render those results.
