Perhaps you should try some spelling variations:
pro{acute}activa » prof{acute}activa, pro{acute}active
pro{acute}tactica » prof{acute}tactica, pro{acute}practica, pro{acute}tlactica, pro{acute}tactina, pro{acute}tpractica
pero{acute}actica » pedro{acute}actica, pero{acute}lactica, pero{acute}actina, pero{acute}practica
peru{acute}lactico » peru{acute}practico

You may be able to get more results by adjusting your search query.

• The words AND, OR and NOT may confuse the search; try adding quotes: "((pro{acute}activa OR pro{acute}tactica) OR (pero{acute}actica OR peru{acute}lactico)) ;~".
• Adding a wildcard symbol may retrieve word variants: ((pro{acute}activa OR pro{acute}tactica) OR (pero{acute}actica OR peru{acute}lactico)) ;*.
