...nested element underneath the field type? I dont know if this is even
possible or a good idea, but its an that would remove some xml files.
i don't think the schema parsing code can handle that – it's attribute based,
not nested element based
{quote}
Right but code can change. Other parts of solr allow this kinda stuff.

yeah ... it would be tempting to not even let the config specify numeric values
– just an ordered list, except:
1) all hell would break loose if someone accidently inserted a new element
anywhere other then the end of the list
2) you'd need/want a way to "disable" values form the middle of the list from
working again.

Well i guess i look at it differently. That this is in a sense like an
analyzer. you cant change the config without reindexing.

I was actually thinking it would be nice to support multiple legal names (with
one canonical for respones) per value, but that would preent the simple array
lookps...
{quote}
Why? I'm talking about int->canonical name (e.g. in the valuesource impl) not
anything else. as far as name->int, you want a hash anyway.

>
> 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.
