I want to understand, why number of requests in SOLD CLOUD is different with and without using of grouping feature.
1. suppose we have several shards in SOLR CLOUD ( lets say 3 shards ) 2. One of them, gets a query with rows = n 3. This shards distributes a request among others and suppose that every shard has a lot of results , much more than n . 4. Then it receives an item IDs from each shards , so the number of results in total is 3n 5. Then it sorts the results and chooses the best n results , when in my case each shard has representatives in total results . 6. Then it send a second request to each shard , with appropriate item IDs , to get a stored fields . So then in this case ,each shard will be queried twice, first one to get item IDs , and the second to get stored fields . That is what I see in my logs . ( I see 6 log entries , 2 for each shard ) *The question is , why when I am using a grouping feature, the number of request to each shard is 3 instead of 2 times ?* ( I see 8 or 9 log entries ) -- View this message in context: http://lucene.472066.n3.nabble.com/Number-of-requests-to-each-shard-is-different-with-and-without-using-of-grouping-tp4224293.html Sent from the Solr - User mailing list archive at Nabble.com.
