The formatter has wrecked the table... Reposting it
Please read it as follows
{ENTITY,PARENT,DATE,SHARD} tuple
M1 C1 12/11/2010 A1
M2 C2 12/11/2011 A2
M3 C4 12/02/2012 A3
M4 C1 12/11/2012 A4
M5 C2 13/11/2012 A4
M6 C3 14/11/2012 A4
I need to group this based on parents ordered by time. The shards
themselves are in increasing order of time {A1-A4 in ascending order of
time}
So, if for some search, the entities matched are M1,M2,M3,M4&M6, the set of
results returned should be *C3,C2,C1,C4*
I am aware of grouping search in lucene, but extending it to multiple
shards is possible? More importantly, are there ways by which I can
re-organize my Documents during index-time to optimize query performance
for such a grouping feature?
