Perhaps you should try some spelling variations:
information collection » information extraction, information communication
collection method » collection methods, collocation method, correction method
array arcing » array forming, array probing, array sharing
array string » array strong, arrays strings, array sharing
method soe » method some, methods soe, method slope

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

• Performing a fuzzy search may retrieve terms with similar spellings: information collection method soe ((((array arcing) OR (array format))) OR (array string))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "information collection method soe ((((array arcing) OR (array format))) OR (array string))".
• Adding a wildcard symbol may retrieve word variants: information collection method soe ((((array arcing) OR (array format))) OR (array string))*.
