• If you are trying to use Boolean operators, they must be ALL CAPS: (( aguas how china's transport asset a ) OR ( guias ((de caso) OR (de casos)) transfer a co ))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "(( aguas how china's transport asset a ) or ( guias ((de caso) OR (de casos)) transfer a co ))~".
• Adding a wildcard symbol may retrieve word variants: (( aguas how china's transport asset a ) or ( guias ((de caso) OR (de casos)) transfer a co ))*.
