Perhaps you should try some spelling variations:
pro{acute}actica » prof{acute}actica, pro{acute}tactica, pro{acute}lactica, pro{acute}activa
pro{acute}lactina » prof{acute}lactina, pro{acute}latina, pro{acute}lactica, pro{acute}lectina, pro{acute}lactiva, pro{acute}lacting
pro{acute}actina » prof{acute}actina, pro{acute}activa, pro{acute}acting
pero{acute}active » pedro{acute}active, peru{acute}active, pero{acute}activa

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

• If you are trying to use Boolean operators, they must be ALL CAPS: ((pro{acute}actica OR (pro{acute}lactina OR pro{acute}actina)) OR pero{acute}active) ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((pro{acute}actica or (pro{acute}lactina OR pro{acute}actina)) or pero{acute}active) ;~".
• Adding a wildcard symbol may retrieve word variants: ((pro{acute}actica or (pro{acute}lactina OR pro{acute}actina)) or pero{acute}active) ;*.
