Eric Pugh commented on SOLR-16220:
----------------------------------
https://search.maven.org/solrsearch/select?q=guice&rows=20&wt=json appears to
work... So does curl
"https://search.maven.org/solrsearch/select?q=fc:org.sonatype.nexus&wt=json";...
Lookinbg a bit more, I don't see a explicit example of the Http2SolrClient
being used...
Would you be interested in submitting a PR to ref guide to add an example about
using this? One neat thing is that we now have the sample code written as
unit tests, that are part of the ref guide, so that would be a great place to
ensure that the examples using the new client work with no hangups...
https://github.com/apache/solr/tree/main/solr/solr-ref-guide/modules/query-guide/examples
is an example...
