Hoss Man commented on SOLR-5084:
--------------------------------

bq. If you want to rename a label, thats fine, but you cant really change the sort order without
reindexing.

No, no .. of course not ... i wasn't suggestiong you could change the order, just:
* *remove* a legal value from the list (w/o causing hte validation to complain)
* add new values to the end of the list
* (as you mentioned) modify the label on an existing value

See the example i posted before about removing "Medium" but keeping "High" & "Critical"
exactly as they are -- no change in indexed data, just a way to tell the validation logic
you were talking about adding "skip this value, i removed it on purpose" (or i suppose: "skip
this value, i'm reserving it as a placeholder for future use")

> 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.
