Perhaps you should try some spelling variations:
using dimensional » one dimensional, high dimensional, n dimensional
information disk » information risk, information desk, information desks
array formulas » area formulas, harrop formulas, array format
array forming » array format, array arcing, array fermi
array string » array strong, arrays strings, array sharing
disk using » risk using, milk using, task using

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

• If you are trying to use Boolean operators, they must be ALL CAPS: information disk using dimensional ((((array forming) OR (array formulas))) OR (array string))~.
• Adding a wildcard symbol may retrieve word variants: information disk using dimensional ((((array forming) or (array formulas))) or (array string))*.
