Hi, 1. No, it’s not valid. Solr will look at schema to see if it can use docValues or if it has to uninvert field and it assumes that all fields will have doc values. You might expect from wrong results to errors if you do something like that. 2. Not sure if it would work, but It is not better than reindexing everything. Lucene segments are immutable and it needs to create new document and flag existing as deleted and purge it at segment merge time. If you are trying to avoid changing collection name, maybe you could do something like that by using aliases: index into new collection, delete existing collection, create alias with old collection name pointing to new collection.
