Perhaps you should try some spelling variations:
information spaces » information sources, information series, information services
main dimensions » domain dimensions, chain dimensions, domains dimensions
array formulas » area formulas, harrop formulas, array format
array string » array strong, arrays strings, array sharing
array arcing » array forming, array probing, array sharing
spaces main » space main, spaces making, spaces domain

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

• Performing a fuzzy search may retrieve terms with similar spellings: information spaces main dimensions ((((array string) OR (array formulas))) OR (array arcing))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "information spaces main dimensions ((((array string) OR (array formulas))) OR (array arcing))*".
