Talvez debería tentar con algunhas variantes ortográficas:
irrigation requirements » irrigation equipment, nutrition requirements
requirements two » requirements do, requirements tools, requirements test
two dimensional » three dimensional
arrays swarming » arrays searching, rats swarming, arrays bearing
array string » array strong, arrays strings, array sharing
array arcing » array forming, array probing, 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: irrigation requirements two dimensional ((arrays swarming) or (((array string) or (array arcing))))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: irrigation requirements two dimensional ((arrays swarming) OR (((array string) OR (array arcing)))).
• Adding a wildcard symbol may retrieve word variants: irrigation requirements two dimensional ((arrays swarming) or (((array string) or (array arcing))))*.
