  • Extract the following jar files from the archives and add to the lib folder in your solr/home (e.g. in the Install, the lib folder would be /home/repository/solr/default/lib/):

  • Add the following field definitions to your schema.xml file:

    <field name="lat" type="sdouble" indexed="true" stored="true"/><!-- must match the latField in solrconfig.xml -->
    <field name="lng" type="sdouble" indexed="true" stored="true"/><!-- must match the lngField in solrconfig.xml -->
    <field name="geo_distance" type="sdouble"/> <!-- Optional but used for distributed searching -->
    <dynamicField name="_local*" type="sdouble" indexed="true" stored="true"/><!-- used internally by localsolr -->
    
  • If you want to use the demo data (or the LocalSolr demo data)…

    • Add the following field definitions to your schema.xml file:

      <field name="cinema" type="text" indexed="true" stored="true"/>

    • Start SOLR and add the data to SOLR:

      java -Durl=http://localhost:8080/solr/update -jar post.jar devon.xml
