• If you are trying to use Boolean operators, they must be ALL CAPS: computation distributed system support ((((array formulas) OR (array string))) OR (array using)).
• Adding a wildcard symbol may retrieve word variants: computation distributed system support ((((array formulas) or (array string))) or (array using))*.
