The second example for a ScriptTransformer in http://wiki.apache.org/solr/DataImportHandler#Transformer should give you an idea of how to proceed: * row.get( 'category' ) gets the field 'category' from the current entity to which the ScriptTransformer is being applied. * Fields from higher-level entities will need to be passed in using DIH variables. E.g., if you have a higher-level entity called 'parent', and are getting data from the current entity via a database select, e.g., <entity... query="select category from mytable"> you will need to modify the query to something like <entity... transformer="script:mytrans" query="select category from mytable, ${parent.id} as id"> and add <field column="id"> inside the current entity (cannot remember now if this is required, or can be dispensed with).
