Ah, the language.... sorry in Hebrew. One is a dropdown for the cities, and the other is a free text where people can type the first or last name of a dentist.
When you choose a city - there are no returns. Nor when you put in a name.
And you are sure the data is there? That the posts have a city assigned, for example?
Could you check one thing?
In the View, make sure that you can see the Query Filter section. If needs be go to the Screen Options tab at the very top of the page and make sure the Query Filter option is checked.
You should see Query Filters for each of the filters you inserted in the Filter Editor (where the value comes from a URL parameter). Is that right?
Let me mark your next reply as private so that I can get log-in credentials from you—you may want to create a temporary admin user for me to use that you can later delete. Perhaps you could edit the profile for that temporary user to use English.
Which View should I be looking at, and where is it displayed?
I looked at the first few dentists to check their data and they don't have a city selected, and if that is the case for your other dentist posts then the city search won't work as the underlying data is missing.
I suspect your name search wasn't working because the type field did not have an option for nothing selected, meaning that you couldn't search just by a name without also specifying the type.
So I updated your View to include a nothing-selected option for the type field, and now the name search works (see screenshot).
So the problem is with the city search, and that appears to be because there is no city selected in the dentist posts.
