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:
| Warning |
|---|
Use the files presented below to add whatever you want to the existing Solr configuration of Datafari. They will never be erased by an update in Datafari if you perform a modification, plus they are automatically included in the default conf. You can save them in order to backup your custom conf and easily port them on other Datafari installations. Keep in mind that if you chose not to use these files and to directly modify the standard solrconfig.xml file and/or schema.xml file, you will have troubles saving and restoring your modifications on a new Datafari installation or an update process. |
solrconfig.xml includes 4 custom files located in {Datafari_Home}/solr/solrcloud/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
| Warning |
|---|
You need to restart Datafari to load the new libs |
custom_request_handlers.incl: Used to add new request handlers. You also need to enter your custom request handlers in the file datafari.properties located in /opt/datafari/tomcat/conf and edit the property userAllowedHandlers. Enter the request handlers separated by a comma.
Code Block nano /opt/datafari/tomcat/conf/datafari.properties
In the file edit this line :Code Block userAllowedHandlers=/newselect,/superSearch- 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 (and restart Datafari if you added some libs)
schema.xml also includes 4 custom files located in {Datafari_Home}/solr/solrcloud/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
| Warning |
|---|
Keep in mind too that we use a managed schema now so for the files in custom_schema, they ONLY will be loaded by launching the script into /opt/datafari/solr/solrcloud/FileShare/conf/addCustomSchemaInfo.sh. |
| Info |
|---|
You can also directly add fields by the Solr Admin UI. But the modifications done will be added in the managed-schema file. If you upgrade Datafari in the future your modifications will be lost. |
