Hi all, I'm running Solr 7.0.1. When I tried to run TopicStream with the following expression
String expression = "topic(checkpointCollection," + "myCollection" + "," + " q=\"*:*\"," + " fl=\"document_id,title,full_text\"," + " id=\"myTopic\"," + " rows=\"300\"," + " initialCheckpoint=\"0\"," + " wt=javabin)"; I got the error java.io.IOException: Slices not found for checkpointCollection Should I create a checkpointCollection on the cluster? And if yes, what is the schema for this collection? I used the topic stream instead of search to fetch all documents with no docValues fields. Thanks, Mahmoud
