Subject [jira] [Commented] (SOLR-5084) new field type - EnumField
Date Wed, 28 Aug 2013 00:09:52 GMT

    [ https://issues.apache.org/jira/browse/SOLR-5084?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13751933#comment-13751933

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.
