Perhaps you should try some spelling variations:
information spaces » information sources, information series, information services
taking decision » taking decisions, making decision, making decisions
array formulas » area formulas, harrop formulas, array format
spaces taking » spaces making, space taking, spaces tracking
array arcing » array forming, array probing, array sharing
array string » array strong, arrays strings, array sharing

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 spaces taking decision ((array formulas) OR (((array arcing) OR (array string))))~".
• Adding a wildcard symbol may retrieve word variants: information spaces taking decision ((array formulas) OR (((array arcing) OR (array string))))*.
