basic dimensions » based dimension, pacific dimensions, design dimensions
processes basic » processes based
array formulas » area formulas, harrop formulas, array format
array forming » array format, array arcing, array fermi
array using » arrays using

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