: Doable at Lucene level by any chance? Given how well the Trie fields compress (ByteField and ShortField have been deprecated in favor of TrieIntField for this reason) it probably just makes sense to treat it as a numeric at the Lucene level.

I've typically dealt with this sort of thing at the client layer using a simple numeric field in Solr, or used an UpdateProcessor to convert the String->numeric mapping when indexing & used clinet logic of a DocTransformer to handle the stored value at query time -- but having a built in FieldType that handles that for you automatically (and helps ensure the indexed values conform to the enum) would certainly be cool if you'd like to contribute it. -Hoss
