Perhaps you should try some spelling variations:
irrigation requirements » irrigation equipment, nutrition requirements
requirements debra » requirements data, requirements dietary, requirements design
debra dimensional » zero dimensional, data dimensional, extra dimensional
arrays » ardays, array, arways
rays » days, ray, ways

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 debra dimensional ((((arrays OR ardays) or ardays) from) or (rays from))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: irrigation requirements debra dimensional ((((arrays OR ardays) OR ardays) from) OR (rays from)).
• The words AND, OR and NOT may confuse the search; try adding quotes: "irrigation requirements debra dimensional ((((arrays OR ardays) or ardays) from) or (rays from))".
• Adding a wildcard symbol may retrieve word variants: irrigation requirements debra dimensional ((((arrays OR ardays) or ardays) from) or (rays from))*.
