Talvez debería tentar con algunhas variantes ortográficas:
determination case » determination based, determination a, determination time
array imaging » arrays imaging, airway imaging, ray imaging
array string » array strong, arrays strings, array sharing
case r » case 2, case 3, case 1
position » positive

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

• Performing a fuzzy search may retrieve terms with similar spellings: position determination case r ((((array string) or (arrays using))) or (array imaging))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: position determination case r ((((array string) OR (arrays using))) OR (array imaging)).
• Adding a wildcard symbol may retrieve word variants: position determination case r ((((array string) or (arrays using))) or (array imaging))*.
