Values on Multiple custom fields in Solspace Super Search

Question

According to the documentation here: https://solspace.com/docs/super_search/search_syntax/#custom_fields

I should be able to pass values from multiple custom fields into my search query. For example, I want to pass the following:

doctors_services-exact=Surgery&doctors_locations-exact=My%20Medical%Center

These custom fields are relationship fields, where I'm trying to filter on the exact title of each relationship. So, I have a service named "Surgery" and a location named "My Medical Center". Trying each one of these individually works - I get the expected results.

Both of these queries work:

doctors_services-exact=Surgery

OR

doctors_locations-exact=My%20Medical%Center

But in combination, it does not work. Any help on this would be great!

UPDATE:

I'm using SuperSearch 2.2.3 and EE 2.10.1. I'm trying to pass two values in the search string - these are the only two search criteria I'm passing - there are no keywords or any other parameters.

This search string is intended to find all doctors with a relationship to a "Generic Hospital Name". It works correctly - the search results show only doctors with a relationship to "Generic Hospital Name":

search&channel=doctors&doctors_locations-exact=Generic%Hospital%Name

This search string is intended to find all doctors with a relationship to "Primary Care". It works correctly - the search results show only doctors with a relationship to "Primary Care":

search&channel=doctors&doctors_services-exact=Primary%20Care

I need to combine these in the event that someone needs to find a doctor specializing in "Primary Care" at "Generic Hospital Name". So, this is my search string for that:

search&channel=doctors&doctors_services-exact=Primary%20Care&doctors_locations-exact=Generic%20Hospital%20Name

This does not work. I get ALL doctors who work at "Generic Hospital Name", however, they are NOT ALL "Primary Care" doctors.

If I remove exact on doctors_services like this:

search&channel=doctors&doctors_services=Primary%20Care&doctors_locations-exact=Generic%20Hospital%20Name

The results for this returns a mixed bag of doctors. The -exact on doctors_locations doesn't limit the doctors from "Generic Hospital Name" nor does it return accurate results for doctors_services. I'd expect to see doctors with services that include the words "Primary" or "Care", but the first doctor in the list specializes in "Lung Transplants" and "Abdominal Surgery".

If I remove -exact from doctors_locations like this:

search&channel=doctors&doctors_services-exact=Primary%20Care&doctors_locations=Generic%20Hospital%20Name

I also get a mixed bag of the results that does not seem to obey either doctors_services or doctors_locations.

Removing exact from both doctors_services and doctors_locations does not produce a comprehensible list of search results either.

So I can pass -exact on doctors_locations OR doctors_services just as long as they do not exist in the same query. doctors_locations-exact works by itself, doctors_services-exact works by itself, but not together.
