Hello, I have heard that there can be issues when using the Solr delete by query approach ( <delete><query>*:*</query></delete>) for large sets of documents. That it may block other indexing activities...
I have also heard that using Solr Streaming Expressions would be a better approach, more efficient for large doc sets to be deleted. I did a quick search for the syntax of a streaming expression for delete, but did not find it. Any tips on how to construct this expression? Thanks, Matthew
