Is it possible to make multiple joins on Solr?

I was able to implement one join (https://wiki.apache.org/solr/Join) in my query but I couldn't find the correct syntax to use multiple joins... is that possible? Could someone please give me some example? Thanks!

Re: SolrJ optimize method -- not returning immediately when the "wait" options are false

https://issues.apache.org/jira/browse/SOLR-2018 There used to be a waitFlush parameter (wait until the IndexWriter has written all the changes) as well as a waitSearcher parameter (wait until a new searcher has been registered... i.e. whatever changes you made will be guaranteed to be visible).

Re: High CPU Usage in export handler

Joel: I did a little work with SOLR-9296 to try to reduce the number of objects created, which would relieve GC pressure both at creation and collection time. I didn't measure CPU utilization before/after, but I did see up to a 11% increase in throughput. It wouldn't hurt my feelings at all to ha

Hmm, that should work fine. Let us know what the logs show if anything because this is weird. Best, Erick On Tue, Nov 8, 2016 at 1:00 PM, Chetas Joshi wrote: > Hi Erick, > > This is how I use the streaming approach. > > Here is the solrconfig block. > > > > {!xport} > xsort

Any more thoughts on this? The longer i look at this situation, the more i’m thinking i’m at fault here - expection something that isn’t to be expected at all? Whatever is on your mind once you’ve read mail - don’t keep to it, let me know. -Stefan On November 7, 2016 at 5:23:58 PM, Stefan Mathe

Re: Challenges with new Solrcloud Backup/Restore functionality

Hi Stephen, Thanks for the update. Regarding SOLR-9527 - I think we need a unit test for verifying "createNodeSet" functionality. I will spend some time on it in next couple of days. Also regarding #2, i also found similar issue (doc count mismatch after restore) while testing with a large colle

Re: Challenges with new Solrcloud Backup/Restore functionality

Just wanted to note that we tested out the patch from SOLR-9527 and it worked perfectly for the balancing issue - thank you so much for that! As for issue #2, we've resorted to doing a hard commit, stopping all indexing against the index, and then taking the backup, and we have a reasonably good

Re: Re-register a deleted Collection SorlCloud

I won't be able to achieve the correct mapping as I did not store the mapping info any where. I don't know if core-node1 was mapped to shard1_recplica1 or shard2_replica1 in my old collection. But I am not worried about that as I am not going to update any existing document. This is what I did.

Re: High CPU Usage in export handler

It sounds like your scenario, is around 25 queries per second, each pulling entire results. This would be enough to drive up CPU usage as you have more concurrent requests then CPU's. Since there isn't much IO blocking happening, in the scenario you describe, I would expect some pretty busy CPU's.

Edismax query parsing in Solr 4 vs Solr 6

I am migrating a solr based app from Solr 4 to Solr 6. One of the discrepancies I am noticing is around edismax query parsing. My code makes the following call: userQuery="+(title:shirts isbn:shirts) +(id:20446 id:82876)" Query query=QParser.getParser(userQuery, "edismax", req).getQuery();
