• If you are trying to use Boolean operators, they must be ALL CAPS: (( ((nato anti) OR (nato ari)) siris, series 11: applied sciences ) OR ((( nato ((asii series) OR (ii series)), 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 anti) OR (nato ari)) siris, series 11: applied sciences ) or ((( nato ((asii series) or (ii series)), series 11: applied sciences ) or ( nato psi series, series 11: applied sciences ))))".
• Adding a wildcard symbol may retrieve word variants: (( ((nato anti) OR (nato ari)) siris, series 11: applied sciences ) or ((( nato ((asii series) or (ii series)), series 11: applied sciences ) or ( nato psi series, series 11: applied sciences ))))*.
