Datafari allows you to add your own Solr configuration to the existing one, without modifying the original configuration files. To do so, both solrconfig.xml and schema.xml files are including custom files that are organized by sections:

Note that if for some reason you need to modify directly the solrconfig.xml file or the schema.xml file, you can do it but we strongly advise you not to do so. These files may change in future versions of Datafari and you will have to manually manage the conflict during the update process.

solrconfig.xml includes 4 custom files located in {Datafari_Home}/solr/solr_home/FileShare/conf/customs_solrconfig:

custom_libs.incl: Used to add new jar libraries that Solr should load. For exemple, to use the ontology feature of Datafari, the Apache Jena lib directory will be added in this file
custom_request_handlers.incl: Used to add new request handlers
custom_search_components.incl: Used to add new searchComponents
custom_update_processors.incl: Used to add new updateProcessors. The updateProcessors that you will specify in this file will be added to the 'datafari' updateRequestProcessorChain (refer to the solrconfig.xml)

These files are not loaded automatically by Solr. As Datafari is using SolrCloud, to take these custom files into account, you must upload them to Zookeeper and then reload the Solr core

schema.xml also includes 4 custom files located in {Datafari_Home}/solr/solr_home/FileShare/conf/customs_schema:

custom_copyFields.incl: Used to add new copyFields to the FileShare core. An example on how to define custom copyField can be found in custom_copyFields.incl.example
custom_dynamicFields.incl: Used to add new dynamicFields to the FileShareCore. An example on how to define custom dynamicField can be found in custom_dynamicFields.incl.example
custom_fields.incl: Used to add new fields to the FileShare core. An example on how to define custom field can be found in custom_fields.incl.example
custom_fieldTypes.incl: Used to add new fieldTypes to the FileShare core. An example on how to define custom field can be found in custom_fieldTypes.incl.example

These files are not loaded automatically in the schema. To do that, you should use the script {Datafari_Home}/solr/solr_home/FileShare/conf/customs_schema/addCustomSchemaInfo.sh to load the custom schemas information in Datafari through the schema API of Solr.
