• If you are trying to use Boolean operators, they must be ALL CAPS: (( nato ari series, series 11: applied sciences ) OR ((( nato ((basic series) OR (((ii series) OR (ii services)))), series 11: applied sciences ) OR ( nato psi series, series 11: applied sciences )))).
• The words AND, OR and NOT may confuse the search; try adding quotes: "(( nato ari series, series 11: applied sciences ) or ((( nato ((basic series) or (((ii series) OR (ii services)))), series 11: applied sciences ) or ( nato psi series, series 11: applied sciences ))))".
• Adding a wildcard symbol may retrieve word variants: (( nato ari series, series 11: applied sciences ) or ((( nato ((basic series) or (((ii series) OR (ii services)))), series 11: applied sciences ) or ( nato psi series, series 11: applied sciences ))))*.
