Perhaps you should try some spelling variations:
functions computations » functions computation, functions computational, function computation
computations complex » computation complexity, computation computer, computational complexity
complex decisions » complex decision, complex designs, complex reactions
array imaging » arrays imaging, airway imaging, ray imaging
array string » array strong, arrays strings, array sharing

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

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