Perhaps you should try some spelling variations:
"azimuth quantum framework" » "azimuth quarkus framework", "azimuth quality framework"
"azimuth quantum plumbers" » "azimuth quantum clusters", "azimuth quantum counters", "azimuth quantum ladders"
"azimuth quantum kramers" » "azimuth quantum games", "azimuth quantum traversal"

You may be able to get more results by adjusting your search query.

• If you are trying to use Boolean operators, they must be ALL CAPS: (("azimuthal quantum number") OR ((("azimuth quantum number") OR ((("azimuth quantum numbers") OR ((("azimuth quantum plumbers") OR ((("azimuth quantum kramers") OR ("azimuth quantum framework")))))))))).
• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"azimuthal quantum number\") or (((\"azimuth quantum number\") or (((\"azimuth quantum numbers\") or (((\"azimuth quantum plumbers\") or (((\"azimuth quantum kramers\") OR (\"azimuth quantum framework\"))))))))))".
• Removing quotes may allow a broader search: (( azimuthal quantum number ) or ((( azimuth quantum number ) or ((( azimuth quantum numbers ) or ((( azimuth quantum plumbers ) or ((( azimuth quantum kramers ) OR ( azimuth quantum framework )))))))))).
• Adding a wildcard symbol may retrieve word variants: (("azimuthal quantum number") or ((("azimuth quantum number") or ((("azimuth quantum numbers") or ((("azimuth quantum plumbers") or ((("azimuth quantum kramers") OR ("azimuth quantum framework"))))))))))*.
