Re: Local development and SolrCloud

Thanks everyone. I think we forgot that cloud doesn’t have to be clustered. That local overhead being avoided makes it a much easier pill to swallow as far as local performance (vs. having all the extra containers running in docker) Will see what we can spin up and ask questions if/as they arise!

Hi, Pratic I believe that your observations are correct. Score for each individual query (in your example it's wildcards query like 'concept_name:(*semantic*)^200') is calculated by a complex formulas (one of possible implementations with a good explanation is described here

Question on query time boosting

That's actually 10,000 ms, a typo in your message? Do you have a situation where that setting is causing you trouble? Because 10 seconds for communications with ZK is quite a long time, I'm curious what the circumstances are that you're seeing. Best, Erick On Wed, Aug 22, 2018 at 3:51 PM, Danny

Shawn, the block cache seems to be off-heap according to https://lucene.apache.org/solr/guide/7_4/running-solr-on-hdfs.html So you have 800G across 4 nodes, that gives 500M docs and 200G index data per solr node and 40G per

Hi, With debugQuery you see the timings. What component spends the most time? With shards.info=true you see what shard is the slowest, if your index is sharded. With echoParams=all you get the full list of query parameters in use, perhaps you spot something? If you start Solr with -v option
