[jira] Updated: (SOLR-1986) Allow users to define multiple subfield
types in AbstractSubTypeFieldType
[ https://issues.apache.org/jira/browse/SOLR-1986?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]
Thomas Joiner updated SOLR-1986:
--------------------------------
Attachment: AbstractMultiSubTypeFieldType.patch
Since the reason people seemed to object to the patch in the mailing list was that the AbstractSubTypeFieldType was not originally intended to be used for multiple different types, I made it a separate class. Also, the subFieldType parameter now works, and the created subFields are prepended with "subtype_" so as to allow dynamicFields to be used to simulate multiValued fields.

> URL: https://issues.apache.org/jira/browse/SOLR-1986
> Project: Solr
> Issue Type: Improvement
> Components: Schema and Analysis
> Reporter: Mark Allan
> Priority: Minor
> Attachments: AbstractMultiSubTypeFieldType.patch, multiSubType.patch

> Original Estimate: 48h

> A few small changes to the AbstractSubTypeFieldType class to allow users to define distinct field types for each subfield. This enables us to define complex data types in the schema.
> For example, we have our own subclass of the CoordinateFieldType called TemporalCoverage where we store a start and end date for an event but now we can store a name for the event as well.
> <fieldType name="temporal" class="uk.ac.edina.solr.schema.TemporalCoverage" dimension="3" subFieldSuffix="_ti,_ti,_s"/>
> In this example, the start and end dates get stored as trie-coded integer subfields and the description as a string subfield.
