Trying to get ALL scores from a previous search in a custom search component ("last-components")

[Darin Amos]

Hello,

I am trying to implement a Rollup Search component on a version of SOLR that 
exists previously to the parent/child additions, so I am trying to implement my 
own. The searches will be executed exclusively against the child documents, and 
I want to “rollup” those child documents into the parent documents. 

The interface is going to allow the user to add the following parameters to the 
SOLR query:

&rollup=true&rollup.parentField=id&rollup.childField=parentId

My code so far is below. What I have works so far, except my second parent 
query loses the order. I would like to be able to sort my parent query by the 
score of the previous child search. Perhaps I would take the highest score from 
all children (haven’t decided yet). My problem however is that I don’t know how 
I can get the score from all the hits in the original search, just what is 
returned. If my child query gets 10,000 hits, but only return 100 records, I 
can’t get all the scores I need.

Does anyone have any recommendations?

Thanks!!
Darin
