Hi,

We are using 4 cores (starting from core 0 to core 4) for parallel indexing
process. We use shards to do distributed indexing and we also use dismax
request handler when doing search.

I have configured core0 as Shards master core.

When I issue a search query (with dismax request handler) on core0, does the
search happens on each core (scoring results separately for each core) and
the result is just a consolidation of the results from each individual core?

Does SOLR uses any other logic (other than just consolidating the results
from each core) in Shards to increase relevancy.. I know that shards doesn't
implement any other distributed scoring as such in version 1.3, just want to
check if there was any enhancements added to version 1.4 with respect to
SOLR distributed scoring??

Also, if I try to sort the query result from shards.. will sorting happens
on the consolidated data or on each individual core data?

I am just trying to figure out best possible way to implement distributed
search without affecting the search relevancy.

Thanks,
Barani
