Perhaps you should try some spelling variations:
information functions » information function, information functional, information foundations
functions different » functions difference, functions differential, cations different
array string » array strong, arrays strings, array sharing
array along » arrays long, array arcing, array paving
arrays load » arrays brad

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

• Performing a fuzzy search may retrieve terms with similar spellings: information functions different densities ((((array along) or (arrays load))) or (array string))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: information functions different densities ((((array along) OR (arrays load))) OR (array string)).
• Adding a wildcard symbol may retrieve word variants: information functions different densities ((((array along) or (arrays load))) or (array string))*.
