Greeting everybody 

I installed fresh copy of dnn 7.2.2

when searching, it gives me, No results found

when I build search index from search admin, it seems successful , but when taking a look at Event Viewer I see:

--------------------------------------------------------------------------

in my PC the default calender was UmAlQuraCalendar, but then I changed it to English calender.

I re-build index again , but the same problem.

I installed another fresh copy of 7.2.2 , nothing changed.

I took a look at IIS Globalization settings and I set both UICulture and Culture to en-us

nothing new.

Any ideas ?
