The second example is a boolean query. if you have a booleanquery(green frog) with a boost of 5, it incorporates its boost into the query norm passed down to its children. So when leaf nodes normalize their weight, it includes all the boosts from the parent hierarchy. You can see what I mean if you look at BooleanWeight.normalize() Because of how this is done, 3.x's explain confusingly only shows the leaf node's explicit boost, since thats all it really knows. To see what i mean try something like booleanquery(green^2 frog^3)^5 In 4.x these boosts are split apart from and kept separate from the query norm, so we could actually improve the explanations here I think. -- lucidimagination.com
