Perhaps you should try some spelling variations:
information documents » information documentation, information agents, information requirements
documents cognates » documents context
cognates extending » context extending
array arcing » array forming, array probing, array sharing
array string » array strong, arrays strings, array sharing
array along » arrays long, array paving, array strong

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 documents cognates extending ((array along) OR (((array arcing) OR (array string))))~".
• Adding a wildcard symbol may retrieve word variants: information documents cognates extending ((array along) OR (((array arcing) OR (array string))))*.
