Thanks for the advice,
I will take a look to see if there is some tuning I can do here, I am not
terribly concerned about that yet anyway.
My concern still remains with how can I get the scores of the entire matched
set. Maybe it is not possible, or perhaps I need to write my own
query/match/scorer to do this.
Curious is anyone else has tried to implement a similar rollup type search
component before.
Thanks!
