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

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

• Performing a fuzzy search may retrieve terms with similar spellings: ((pro{acute}actica or (pro{acute}lactina OR prof{acute}lactina)) or pero{acute}activa) ;~.
• If you are trying to use Boolean operators, they must be ALL CAPS: ((pro{acute}actica OR (pro{acute}lactina OR prof{acute}lactina)) OR pero{acute}activa) ;*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((pro{acute}actica or (pro{acute}lactina OR prof{acute}lactina)) or pero{acute}activa) ;*".
