Selected Index type properties are not displayed/added in the Enterprise search

Hello,

Apart from default search properties we added few other properties of an Item type in the enterprise search Indexed type properties but these properties are not displayed in the search. Some of these properties are Items from different Item types so we included or made the configuration as per the documentation to include them part of search but no luck.

I would highly appreciate if any suggestions or some more documentation provided regarding this.

Thanks,

Vivek
