Perhaps you should try some spelling variations:
operation function » operations function, operational functions, operator functions
function different » functions different, functions difference, conation different
different versions » different regions, different seasons, different sections
array sharing » array string, arrays bearing, array imaging
array using » arrays using
array long » array along, arrays long, array strong

You may be able to get more results by adjusting your search query.

• Performing a fuzzy search may retrieve terms with similar spellings: operation function different versions ((((array long) or (array using))) or (array sharing))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: operation function different versions ((((array long) OR (array using))) OR (array sharing)).
• Adding a wildcard symbol may retrieve word variants: operation function different versions ((((array long) or (array using))) or (array sharing))*.
