Hi, Again, I will ask a Long-Time question, It has been asked for many time,
but I googled a lot , but no good solution:

Hi，All：
I want to ask a question, How does Solr implements Paging, such as start =
100 and row = 20
I roughly saw Solr source, hare is the code:
getDocListNC(QueryResult qr,QueryCommand cmd) ;
often it uses :

o Lucene , forgive me for my ignoring.

Hi All:
I want to ask how to do "Group by on multi fields ".
The Lucene JavaDOC only gives a demo about how to group by a single-field.
Would anybody give me a hint?
