It does appear that the logs are being truncated by the logger: https://logging.apache.org/log4j/log4j-2.8/log4j-core/apidocs/org/apache/logging/log4j/core/pattern/MaxLengthConverter.html .
But, I've created a ticket to selectively suppress certain parameters in the logs: https://issues.apache.org/jira/browse/SOLR-16710 On Mon, Mar 20, 2023 at 10:09 AM Joel Bernstein <joels...@gmail.com> wrote: > I've run into an issue with KNN vector queries and the Solr logs.
