• If you are trying to use Boolean operators, they must be ALL CAPS: ((prof{acute}practica OR (prot{acute}cticas OR pro{acute}cticas)) OR proud{acute}tactica) ;.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((prof{acute}practica or (prot{acute}cticas OR pro{acute}cticas)) or proud{acute}tactica) ;".
• Adding a wildcard symbol may retrieve word variants: ((prof{acute}practica or (prot{acute}cticas OR pro{acute}cticas)) or proud{acute}tactica) ;*.
