   @noblepaul Good point:
   
   1. **bin/solr start**
   2. Edit the default configset's add-schema-fields definition to
       - Replace AddSchema... with GuessSchema... URP
       - Remove _default_ parameter (code automatically widens to "String" as last step)
       - Remove _Integer_ mapping, where _Long_ already exists (code automatically widens to nearest acceptable definition for numerics)
   3. **bin/solr create -c guess**
   4. **bin/post -c guess -params "guess-schema=true" example/exampledocs/*.xml**
   5. As post does indexing and then commit, it triggers both phases of the URP
   6. At the point, the schema is created (based on all data) but nothing is actually indexed; the user can review and adjust the schema without any issues
   7. Flag value can actually be anything for now, in the future I was thinking that maybe this could be a tag to mark new fields (see SOLR-14855)
   8. **bin/post -c guess  example/exampledocs/*.xml**
   9. Now the data is entered and can be searched
   10. **bin/post -c guess -params "guess-schema=true" example/films/films.json**
   11. **bin/post -c guess  example/films/films.json**
   12. This shows that we don't need the "extra steps" instructions, the films example current requires.
