Perhaps you should try some spelling variations:
nutrient requirements » nutritional requirements
requirements first » requirements finish, requirements from, requirements free
first dimensional » first dimension, finite dimensional, five dimensional
array strings » array strong, array sharing
array string » array strong, array sharing, array forming

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

• Performing a fuzzy search may retrieve terms with similar spellings: nutrient requirements first dimensional ((((array strings) OR (array string))) or (arrays strings))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: nutrient requirements first dimensional ((((array strings) OR (array string))) OR (arrays strings)).
• The words AND, OR and NOT may confuse the search; try adding quotes: "nutrient requirements first dimensional ((((array strings) OR (array string))) or (arrays strings))".
• Adding a wildcard symbol may retrieve word variants: nutrient requirements first dimensional ((((array strings) OR (array string))) or (arrays strings))*.
