Perhaps you should try some spelling variations:
irrigation equipment » purification equipment, irrigation development, application equipment
equipment based » equipment used, equipment case, equipment leases
based precision » based decision, based prediction, based decisions
array profiling » array processing, microarray profiling
array arcing » array forming, array probing, array sharing
array string » array strong, arrays strings, array sharing

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 equipment based precision ((((array arcing) OR (array string))) OR (array profiling))~".
• Adding a wildcard symbol may retrieve word variants: irrigation equipment based precision ((((array arcing) OR (array string))) OR (array profiling))*.
