Hi all, We are having solr architecture as below. *We are facing the frequent replication failure between master to repeater server as well as between repeater to slave servers.* On checking logs found every time one of the below exceptions occurred whenever the replication have failed. 1) [image: image.png] 2) [image: image.png] 3) [image: image.png] The replication configuration of master,repeater,slave's is given below: [image: image.png] Commit Configuration master,repeater,slave's is given below : [image: image.png] Replication between master and repeater occurs every 10 mins.

Frequent Index Replication Failure in solr.
Hi team,
We are having solr architecture as *master->repeater-> 3 slave servers.*
We are doing incremental indexing on the master server(every 20 min) .
Replication of index is done from master to repeater server(every 10 mins)
and from repeater to 3 slave servers (every 3 hours).
*We are facing the frequent replication failure between master to repeater
server as well as between repeater to slave servers.*
On checking logs found that every time one of the below exceptions
occurred whenever the replication has failed .

Solr collapse & expand queries.
Hi community,
I want to implement collapse queries instead of group queries . In solr
documentation it is stated that we should prefer collapse & expand queries
instead of group queries.Please explain how the collapse & expand queries
is better than grouped queries ? How can I implement it ? Do i need to add
anything in *solrconfig.xml file* as well or just need to make changes in
solr queries like below:
*fq={!collapse field=*field*}&expand.rows=n&expand=true instead of
group.field=*field*&group=true&group.limit=n*
I have done performance testing by making above changes in solr queries and
found that query times are almost the same for both collapse queries and
group queries.
Please help me how to implement it and its advantage over grouped queries.
Thanks,
Parshant Kumar.

Queries Regarding Cold searcher
Hi all, Please help me in below queries: 1) what is the impact of making cold searcher false,true? 2)After full replication completion of data on slave server, new searcher is opened or not? 3)If opensearcher is false in autocommit and cold searcher is true , what does this conclude , Is their any interconnection between both of them? Thanks Parshant --
Re: Queries Regarding Cold searcher
Adding more queries :- Do value(true or false) of cold searcher play any role during the completion of replication on slave server.If not please tell in which process in solr its applied?

Increase in response time in case of collapse queries.
Hi all, We have implemented collapse queries in place of grouped queries on our production solr. As mentioned in solr documentation collapse queries are recommended in place of grouped queries in terms of performance . But after switching to collapsed queries from grouped queries response time of queries have increased. This is unexpected behaviour, the response time should have been improved but results are opposites. Please someone help why response time is increased for collapsed queries. Thanks Parshant Kumar --
