  • This is the correct solr query. There must be issue in dotnet code while creating query to Solr. Can you share that solr predicate builder code. There must be an error on the predicate builder.

  • We are getting the same error like in this article community.sitecore.com/community/…. But we never used the || condition and only used the aggregate with or condition. Are there any troubleshooting steps available?
