Perhaps you should try some spelling variations:
irrigation development » organization development, application development, formulation development
development two » development tool, development tools, development timor
two dimensional » three 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.

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