array string » array strong, arrays strings, array sharing
array using » arrays using
a extended » _ extended, 2 extended, 3 extended

• The words AND, OR and NOT may confuse the search; try adding quotes: "informatics a extended conventional ((arrays a) OR (((array using) OR (array string))))".
• Adding a wildcard symbol may retrieve word variants: informatics a extended conventional ((arrays a) OR (((array using) OR (array string))))*.
