• If you are trying to use Boolean operators, they must be ALL CAPS: (("sans-more advanced control") OR ((("sans-lte advanced control") OR ("sons-lte advanced control")))).
• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"sans-more advanced control\") or (((\"sans-lte advanced control\") OR (\"sons-lte advanced control\"))))".
• Removing quotes may allow a broader search: (( sans-more advanced control ) or ((( sans-lte advanced control ) OR ( sons-lte advanced control )))).
• Adding a wildcard symbol may retrieve word variants: (("sans-more advanced control") or ((("sans-lte advanced control") OR ("sons-lte advanced control"))))*.
