Perhaps you should try some spelling variations:
interflation functions » interpolation functions, integration functions, interpolation functional
functions difference » functions different, functional differences, function inference
difference versions » different versions, difference dimensions, reference version
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: interflation functions difference versions ((((array long) or (array using))) or (array sharing))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: interflation functions difference versions ((((array long) OR (array using))) OR (array sharing)).
• Adding a wildcard symbol may retrieve word variants: interflation functions difference versions ((((array long) or (array using))) or (array sharing))*.
