Perhaps you should try some spelling variations:
information summarization » information formalization, information polarization, information popularization
summarization efficient » scalarization efficient, communication efficient, visualization efficient
efficient caching » efficient teaching, efficient machine, efficient searching
array probing » arrays probing, assay probing, array profiling
array string » array strong, arrays strings, array sharing
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: information summarization efficient caching ((((array long) or (array probing))) or (array string))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: information summarization efficient caching ((((array long) OR (array probing))) OR (array string)).
• Adding a wildcard symbol may retrieve word variants: information summarization efficient caching ((((array long) or (array probing))) or (array string))*.
