Re: How to assign a hash range via zookeeper?

Shawn, Thanks - this is very helpful. I found the state.json file and it indeed shows that the range for shard1 is null. In order to fix, do I need to upload a corrected state.json file with corrected hash ranges? How can I do that? (zkcli.sh?) Thanks, Aki On Thu, Feb 4, 2016 at 4:10 PM,

Hi group, While exploring Solr 5.4.0, I noticed a subtle difference in the EXPLAIN debug information, compared to the version we currently use (4.10.1). Solr 4.10.1: 2.0739748 = (MATCH) max plus 1.0 times others of: 2.0739748 = (MATCH) weight(text:test in 30) [DefaultSimilarity], result of:

Re: Errors During Load Test

What is your solr setup -- nodes/shards/specs? 7221 requests/min is a lot so it's likely that your solr setup simply isn't able to support this kind of load which results in the requests timing out which is why you keep seeing the timeout and connect exceptions. On Thu, 4 Feb 2016, 20:30 Tiwari,

Re: implement exact match for one of the search fields only?

The desired architecture is that you use a middle app layer that clients send queries to and that middle app layer then constructs the formal query and sends it on to Solr proper. This architecture also enables breaking a user query into multiple Solr queries and then aggregating the results.

Hi All, We did our first load test on Search (Solr) API, and started to see some errors after 2000 Users. Errors used to go away after 30 seconds, but keep happening frequently. Errors were "java.net.SocketTimeoutException" and "org.apache.http.conn.HttpHostConnectException". We were using

Solr 5: not loading shards from symlinked directories

I've tried to upgrade from Solr 4.10.3 to 5.4.1. Solr shards are placed on different disks and symlinks (ln -s) are created to SOLR_HOME (SOLR_HOME itself is set as an absolute path and works fine). When Solr starts, it loads only shards placed in home directory, but not symlinked ones. If I copy

Thanks Emir and Benedetti. Yes, I'm already on SolrCloud, so I'll probably stick to that. Regarding the network, I am just afraid that when the replica code copies the index over from the main node, it will use up all the available bandwidth, and causes the search query to have little bandwidth

Only INFO level, so I suspect not bad... If that Overseer closed, another node should have picked up where it left off. See that in another log? Generally an Overseer close means a node or cluster restart. This can cause a lot of DOWN state publishing. If it's a cluster restart, a lot of those

Re: Errors During Load Test

The short form is "add more replicas", assuming you're using SolrCloud. If older-style master/slave, then "add more slaves". Solr request processing scales pretty linearly with the number of replicas (or slaves). Note that this is _not_ adding shards (assuming SolrCloud). You usually add shards
