Perhaps you should try some spelling variations:
information spaces » information sources, information series, information services
using dimensions » using dimension, using dimensional, using dimensionless
array formats » array format, assay formats, array formulas
array forming » array format, array fermi, array string
spaces using » space using, surfaces using
array arcing » array probing, array sharing, array using

• If you are trying to use Boolean operators, they must be ALL CAPS: information spaces using dimensions ((((array formats) OR (array arcing))) OR (array forming)).
• Adding a wildcard symbol may retrieve word variants: information spaces using dimensions ((((array formats) or (array arcing))) or (array forming))*.
