Subject [jira] Created: (SOLR-1986) Allow users to define multiple subfield types in AbstractSubTypeFieldType

Allow users to define multiple subfield types in AbstractSubTypeFieldType
-------------------------------------------------------------------------

                 Key: SOLR-1986
                 URL: https://issues.apache.org/jira/browse/SOLR-1986
             Project: Solr
          Issue Type: Improvement
          Components: Schema and Analysis
            Reporter: Mark Allan
            Priority: Minor


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.
