The big addition in 9.x is the Vector Search via DenseVectorField fieldType and K-Nearest-Neighbor (KNN) Query Parser which I'd like to experiment with, e.g. for #84 .

I think the upgrade is likely to be a much bigger undertaking than previous Solr upgrade, because it is likely to require a reindex, and at the moment a full index of all the sites takes several days.

Some notes from 9.1.0 testing:

  • Given I use the Classic Schema, https://issues.apache.org/jira/browse/SOLR-16203 means all the filter name="..." have to be replaced with filter class="..." in schema.xml.
  • The new default highlight method (hl.method) seems to stop hl.fragsize from working correctly. Setting the hl.method to "original" resolves.
  • Unfortunately https://issues.apache.org/jira/browse/SOLR-16585 breaks the Random Page. It is fixed in the forthcoming 9.1.1. Options are therefore to wait for 9.1.1 or rollout 9.1.0 and temporarily disable Random Page.
