Robert Muir commented on SOLR-5084:
-----------------------------------
I still really don't think we should add an enumerated type that isn't strict
about inputs actually matching enumerated values: it loses all of its value to
me.
There are a few inconsistencies where string inputs aren't mapped into their
numeric value: like ValueSourceScorer.getRangeScorer and getRangeQuery in the
fieldtype (in some cases).
I don't understand the need for an analysis chain: The TrieTokenizerFactory is
unnecessary and I have a patch to remove it on some issue somewhere but just
havent gotten around to committing it.
And I still would really like it if we didn't need a separate XML file for each
enumerated type: its like a parallel schema.xml: I think it would be much
better if we could nest this underneath the fieldtype.
Finally, I still think the ordinals should be implicit in the list (as i
mentioned before). This way the thing can actually be efficient.

> We have encountered a use case in our system where we have a few fields
> (Severity. Risk etc) with a closed set of values, where the sort order for
> these values is pre-determined but not lexicographic (Critical is higher than
> High). Generically this is very close to how enums work.
> To implement, I have prototyped a new type of field: EnumField where the
> inputs are a closed predefined set of strings in a special configuration
> file (similar to currency.xml).
> The code is based on 4.2.1.
