Perhaps you should try some spelling variations:
irrigation requirements » irrigation equipment, nutrition requirements
requirements file » requirements free, requirements failure, requirements penile
file decision » agile decision, time decision, fate decision
based openmp » based open, nested openmp, tasks openmp
based opengl » based open
based openg » based open

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: irrigation requirements file decision ((based openg) OR (((based openmp) OR (based opengl))))~.
• Adding a wildcard symbol may retrieve word variants: irrigation requirements file decision ((based openg) or (((based openmp) or (based opengl))))*.
