[jira] [Commented] (SOLR-4503) Add REST API methods to get schema
information: fields, dynamic fields, and field types
[ https://issues.apache.org/jira/browse/SOLR-4503?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13591784#comment-13591784 ]

------------------------------------
Looking good Steve!
It seems like there are multiple use-cases for the fields API...
- One just wants to get all the info/properties for a field, and they don't care how that field is defined.
For example, they may want to look up field X to see if it's indexed, w/o having to worry about if it's a "dynamic" field or not.
- One wants to get the actual definition definition in the schema (or as close to that as possible), and they would expect to see something very close to what they defined (or sent in using the fields API to create a new field). Showing all possible field properties like "storeOffsetsWithPositions" are going to be potentially confusing since people won't know what they mean and when/why they have to specify them when creating new fields.
It may be possible to satisfy everything with the same API by:
- only returning non-default properties... so if you create an integer field with "indexed=true", that's pretty much all you get back.
- having a parameter to allow requesting all "look through" properties.
- allowing the fields API to be used for dynamic fields also, but provide an indicator about what pattern matched

We should aim for being able to hit any node in the cluster w/o worrying about which nodes are hosting which collections.
We should probably also default to indented JSON output.
