Subject [jira] Updated: (SOLR-1986) Allow users to define multiple subfield types in AbstractSubTypeFieldType
Date Wed, 25 Aug 2010 20:54:22 GMT

]

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.

> 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.
