Hi Jay, I can't speak to why you're seeing a performance change between 6.x and 8.x. What I can suggest though is an alternative way of formulating the query: you might get different performance if you run your query using Solr's "terms" query parser: https://lucene.apache.org/solr/guide/8_5/othe

Jochen, For the standard query parser, pure negative queries (no positive query in front of it, such as "*:*") are only allowed as a top level clause, so not nested within parenthesis. Check the second bullet point of the this section of the Ref Guide page for the Standard Query Parser.

In a word, “no”. It’s a whole ’nother architecture to deal with shards, and stand-alone (i.e. master/slave) has no concept of that. You could make a single-shard collection in SolrCloud, copy the index to the right place (I’d shut down Solr while I copied it), and then use SPLITSHARD on it, but th
