Talvez debería tentar con algunhas variantes ortográficas:
irrigation requirements » irrigation equipment, nutrition requirements
requirements from » requirements _, requirements a
from decision » from vision
based openg » based opengl, based openmp
based open » based one, based oxygen
nested » tested

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

• Performing a fuzzy search may retrieve terms with similar spellings: irrigation requirements from decision ((((based openg) OR (based open))) or (nested openmp))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: irrigation requirements from decision ((((based openg) OR (based open))) OR (nested openmp)).
• The words AND, OR and NOT may confuse the search; try adding quotes: "irrigation requirements from decision ((((based openg) OR (based open))) or (nested openmp))".
• Adding a wildcard symbol may retrieve word variants: irrigation requirements from decision ((((based openg) OR (based open))) or (nested openmp))*.
