Perhaps you should try some spelling variations:
nutrient requirements » nutritional requirements
requirements two » requirements do, requirements tools, requirements test
two dimensional » three dimensional
bioarray from » bioarrays from, microarrays from
microarray a » microarrays a, microarray _, microarray dna
rays » days, ray, ways

• If you are trying to use Boolean operators, they must be ALL CAPS: nutrient requirements two dimensional ((((bioarray from) OR (microarray a))) OR (rays from)).
• Adding a wildcard symbol may retrieve word variants: nutrient requirements two dimensional ((((bioarray from) or (microarray a))) or (rays from))*.
