I am trying to create search page for a specific document library
Create result source and page with search results web part to use this result source.
{SearchBoxQuery} {?{searchTerms} Path:{https://SharePoint2013/sites/Projects/Project Documents}}
but I do not get any results. is possible to restrict results to a particular document library?
When calling the path command you should note use the parentheses. Instead use quotes around the path variable so it looks like… Path:”https://domain/sites/library”
