Do "Studied target" bonuses stack with weapon enchantment?

Hey guys!
this is unclear to me, i know that most bonuses don't stack with themselves, but the "Studied target" text says "A slayer can study an opponent he can see as a move action. The slayer then gains a '...' and a +1 bonus on weapon attack and damage rolls against it. "

It doesn't specify what bonus this is, but since its both attack and damage (like enchantment) i was wondering what is the common verdict on this

It might be a bit hard to find, but on the d20pfsrd glossary it says under Bonus that "Bonuses without a type always stack, unless they are from the same source."

In this case, Studied Target is, as you noted, an untyped bonus, and as such it should stack with everything other than itself (so, you can't study someone twice for twice the bonuses).
