This document discusses a problem with searching in SharePoint when searching for keywords within specific document types defined in a custom list column. The problem occurs because SharePoint does not automatically map the custom column to enable filtering search results by the document type.
The solution is to create a managed property mapping in SharePoint search settings that links the custom column to a crawled property. After configuring the mapping and performing a full crawl, searches can then successfully filter results by specifying the document type in addition to keywords.
The tutorial walks through setting up a test environment with a document library and custom column. It demonstrates the search problem, defines the issue, and provides the steps to create the managed property mapping and verify searches now return properly
