Perhaps you should try some spelling variations:
information abstraction » information extraction, information abstracts, information instruction
abstraction task » abstraction case, abstraction fast, abstraction based
task dimension » task dimensions, fast dimension, based dimension
array string » array strong, arrays strings, array sharing
array using » arrays using

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

• The words AND, OR and NOT may confuse the search; try adding quotes: "information abstraction task dimension ((array string) OR (((array using) OR (array format))))~".
• Adding a wildcard symbol may retrieve word variants: information abstraction task dimension ((array string) OR (((array using) OR (array format))))*.
