fq * vs [* TO *]

Hi all, talking about how to write solr queries I was investigating if there is a difference of performance in these two filter queries: field:[* TO *] or field:* In other words: q=*:*&fq=field:[* TO *]&rows=0 q=*:*&fq=field:*&rows=0 Could someone enlighten me? -- Vincenzo D'Amore

Re: fq * vs [* TO *]

Hello, Vincenzo. I traced both code pathes, they are different. It's hard to predict the difference between them. Probably some thorough microbenchmark can show two times fold or so, but don't think it's significant for practical usage. On Thu, Sep 19, 2019 at 10:23 AM Vincenzo D'Amore wrote: >

Re: Solr query fetching different results

Multiple replicas of the same shard will execute their autocommits at different wall clock times. Thus there may be a _temporary_ time when newly-indexed document is found by a query that happens to get served by replica1 but not by replica2. If you have a timestamp in the doc, and a soft commit in

Re: Custom update processor not kicking in

_Why_ is reindexing not an option? 200M doc isn't that many. Since you have Atomic updates working, you could easily write a little program that pulled the docs from you existing collection and pushed them to a new one with the new schema. Do use CursorMark if you try that You have to be ready

Re:Solr query fetching different results

Your query seems simple enough that this may not be your issue, but just mentioning it: Your collection has 1 shard. Depending on how the query is sent, queries to 1 shard collections can sometimes get interpreted as a "distributed query" and sometimes as a "non-distributed query". These have d

Reloading after creating a collection

Hi, Why is it that I need to reload collection after I created it? CDCR runs into issues if I do not do this.

Solr behaves wonky when zookeeper quorom is messed up.

In our PROD SOLR cluster(7.6 and ZK:3.4.9) when Zookeeper leader fails Zookeeper enter an infinite leader election loop which makes SOLR instable. Solr Fails to index(as Expected with error "Remote error message: Cannot talk to ZooKeeper - Updates are disabled") and CPU spikes up. This is a know

Re: Solr behaves wonky when zookeeper quorom is messed up.

If ZK loses quorum, Solr goes read-only. That's how it's designed to work. I don't know of any workaround for that. That makes sense. CPU spiking in solr is because solr's index calls are holding threads because zookeeper is down as per solr? -- Sent from: https://lucene.472066.n3.nabble.com/

Re: Custom update processor not kicking in

Eric, The 200 million docs are all large as they are content indexed. Also it would be hard to convince the customer to rebuild their index. But more than that, I also want to clear my understanding on this topic and know if it’s an expected behaviour for a distributed update processor to not call
