Configuring DSE Search

Changing maxBooleanClauses and configuring the update log.

Configure virtual nodes before starting to use DSE Search/Solr. By default, DataStax Enterprise turns off virtual nodes (vnodes). If want to you use vnodes on Solr nodes, DataStax recommends a range of 32 to 64 vnodes, which increases overhead by approximately 30%.

Changing maxBooleanClauses

A change to the maxBooleanClauses parameter in the solrconfig.xml requires restarting nodes to make the change effective. Merely reloading the Solr cores does not suffice for this parameter.

Configuring the update log

The Solr update log is not supported because Cassandra provides the functionality. If you still want to configure the update log, or you are upgrading a core that is configured to contain the update log, add the force="true" attribute to the configuration element as follows, upload the new Solr configuration, and reload the core:

<updateLog force="true">...</updateLog>
