Perhaps you should try some spelling variations:
information detection » information section, information depreciation, information extraction
detection methods » detection method, extraction methods, collection methods
methods robert » methods robust, methods recent, methods report
array string » array strong, arrays strings, array sharing
array fermi » array forming, array format
array using » arrays using

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

• If you are trying to use Boolean operators, they must be ALL CAPS: information detection methods robert ((((array string) OR (array fermi))) OR (array using))~.
• Adding a wildcard symbol may retrieve word variants: information detection methods robert ((((array string) or (array fermi))) or (array using))*.
