Within my search results web part in SharePoint, I went into the web part properties, and opened up Query Builder. The following query works awesome in Query Builder...
{SearchBoxQuery} MyDocTagsOWSTEXT:chart
..as it finds all items in my document library that has "chart" text associated to the MyDocTags column. So how can I make this live? What left do I need to do, to always have {SearchBoxQuery} filter results based on MyDocTagsOWSTEXT???
My SharePoint search box and search results web parts are both on the same publishing page.
I feel like I am so close! :)
