Subject [jira] [Commented] (SOLR-5084) new field type - EnumField
Date Tue, 13 Aug 2013 11:30:49 GMT

    [ https://issues.apache.org/jira/browse/SOLR-5084?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13738098#comment-13738098

Erick Erickson commented on SOLR-5084:
--------------------------------------

Ahhh, OK. Then Hoss says sorting, so no wonder I'm confused!

There's no reason one couldn't sort by a field of this type, right? Frankly though, it seems
kind of low-utility since there are probably only going to be a few values in the common use-case,
but I'd guess it's still a possibility...

> 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.
