information process » information processes, formation process, information processing
tree dimensional » three dimensional, three dimentional, three dimensionally
array formulas » area formulas, harrop formulas, array formats
process tree » process free, process true, processes tree
array string » array strong, arrays strings, array sharing

• If you are trying to use Boolean operators, they must be ALL CAPS: information process tree dimensional ((((array formulas) OR (array format))) OR (array string)).
• Adding a wildcard symbol may retrieve word variants: information process tree dimensional ((((array formulas) or (array format))) or (array string))*.
