I pulling list of documents through search results WebPart in SharePoint.
I am writing this query and it is working fine
path:"http://server-sharep/abc/*" FileExtension:pdf (IsDocument:"True" OR contentclass:"STS_ListItem")
I have created a custom list and attached with the document library and named it DocumentCategories and Attached the category from this custom list to specific documents.
Now the issue is, I can't find DocumentCategories under 'Property filter' so I could use the filter and pull specific documents based on the categories.
However, I have doubled check the custom library DocumentCategories is searchable as I have checked the settings under
"General Settings > Advanced Settings".
What do I have to do in order to make custom list DocumentCategories to appear under the filter in Search Result WebParts?
