Perhaps you should try some spelling variations:
irrigation requirements » irrigation equipment, nutrition requirements
requirements a » requirements _
array imaging » arrays imaging, airway imaging, ray imaging
array string » array strong, arrays strings, array sharing
a dimension » _ dimension, new dimension
array along » arrays long, array arcing, array paving

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

• The words AND, OR and NOT may confuse the search; try adding quotes: "irrigation requirements a dimension ((((array along) OR (array string))) OR (array imaging))~".
• Adding a wildcard symbol may retrieve word variants: irrigation requirements a dimension ((((array along) OR (array string))) OR (array imaging))*.
