Exclude modified by and created by from search results in SharePoint Online

Question

Is it possible to exclude the properties "Modified by" and "Created by" from the search results? Usually I would go to "Edit Crawled Property" and then uncheck the box "Include in full-text index, but it's greyed out. Any hint or suggestion is welcome.

Answer 1

By default they are mapped to an ows_Created_0x0020_By and ows_Modified_0x0020_By crawled properties.

I think you could remove this mapping. If this doesn't work you can delete the Managed Property itself, although I would avoid this if you can.

In addition, you can try to open the ows_Created_x0020_By crawled property, and uncheck the box “Include in full-text index”. Then , do the same for ows_Modified_0x0020_By.
