Thanks Chris I'll provably try passing the MultiSearcher instance as a parameter so that I can use subDoc and so. It makes sense though to have a getIndex() method inside hit or document that returns some information about where that hit or document belongs to. Do you think that is reasonable to

Hi, You mentioned: "The Hits class normalizes scores by dividing all scores by the highest score, if that highest score is above 1.0." Can you explain what highest score are we talking about? I think there's only one score for a query and doc right? Thanks Yonik Seeley wrote: On 3/3/06, Euge
