How to change solr.maxBooleanClauses limit in Solr 8.11 in Solr cloud mode

["Su, Weiling" <we...@fitchsolutions.com.INVALID>]

We have a need to set the maxBooleanClauses=10240 with Solr 8.11 in solr cloud mode.  We overwrite the system variable default through solrcloud.yaml file and rolling restart the severs one by one. The new System variable is shown up in Solr admin’s Java properties page. But it has no effect on Solr query. We still see the error in log.

too many boolean clauses

solrconfig.xml: <maxBooleanClauses> of 10240 is greater than global limit of 1024 and will have no effect set 'maxBooleanClauses' in solr.xml to increase global limit


I checked the documentation, it seems that Solr Cloud is using zookeeper to store solr.xml. (https://solr.apache.org/guide/8_11/format-of-solr-xml.html#defining-solr-xml).

Any ideas on how to make the above configuration changes to reach Solr query?

Thank you,

Weiling

SolrCloud *CAN* read solr.xml from zookeeper.  But it will only do so if 
you put solr.xml in your zookeeper.  If you don't, then it will look in 
the solr home for it in the exact same manner that Solr does when NOT 
running in cloud mode.

The solr.xml file is the recommended place to define that setting, not 
solrconfig.xml, due to the way that Lucene implements the setting.

If your solr.xml looks exactly like the version shown in that 
documentation page, then you can set a solr.max.booleanClauses system 
property on the java commandline at Solr startup, and it will be used by 
that solr.xml instead of 1024.

My solr.xml contains this line -- the value is completely hard-set and 
cannot be changed with properties:

   <int name="maxBooleanClauses">4096</int>

Thanks,
