[opencms-dev] solr property mapping, multivalue

[Rüdiger Kurz]

Hi Carl-Erik,

1. Add a field 'yourFieldName' to the schema.xml

2. Adjust, compile and add the attached class example to the classpath

3. Adjust the Solr field config of your index (opencms-search.xml)

<fieldconfiguration 
class="org.opencms.search.solr.CmsSolrFieldConfiguration">
   <name>your_solr_config</name>
   <description>The Solr field configuration.</description>
     <fields>
       <field name="yourFieldName">
         <mapping type="dynamic"
                  class="your.package.CmsDynamicDummyField">
           special
         </mapping>
       </field>
     </fields>
</fieldconfiguration>

Good luck!
