Dedupe Sharded Search Results by Shard Order or Score
-----------------------------------------------------
Key: SOLR-1537
URL: https://issues.apache.org/jira/browse/SOLR-1537
Project: Solr
Issue Type: Improvement
Components: search
Affects Versions: 1.4, 1.5
Environment: All
Reporter: Dennis Kubes
Fix For: 1.4, 1.5
Allows sharded search results to dedupe results by ID based on either the order
of the shards in the shards param or by score. Allows the result returned to
be deterministic. If by shards then shards that appear first in the shards
param have a higher precedence than shards that appear later. If by score then
higher scores beat out lower scores. This doesn't allow multiple duplicates
because currently SOLR only permits a single result by ID to be returned.
