Apache Solr Reference Guide Covering Apache Solr 6.0

Datasources can still be specified in solrconfig.xml. These must be specified in the defaults section of the
handler in solrconfig.xml. However, these are not parsed until the main configuration is loaded.
The entire configuration itself can be passed as a request parameter using the dataConfig parameter rather
than using a file. When configuration errors are encountered, the error message is returned in XML format.
A reload-config command is also supported, which is useful for validating a new configuration file, or if you
want to specify a file, load it, and not have it reloaded again on import. If there is an xml mistake in the
configuration a user-friendly message is returned in xml format. You can then fix the problem and do a reloadconfig.
You can also view the DIH configuration in the Solr Admin UI and there is an interface to import content.
Request Parameters
Request parameters can be substituted in configuration with placeholder ${dataimporter.request.paramn
ame}.
Then, these parameters can be passed to the full-import command or defined in the section in sol
rconfig.xml. This example shows the parameters with the full-import command:
dataimport?command=full-import&jdbcurl=jdbc:hsqldb:./example-DIH/hsqldb/ex&jdbcuse
r=sa&jdbcpassword=secret
Data Import Handler Commands
DIH commands are sent to Solr via an HTTP request. The following operations are supported.
Command
abort
delta-import
Description
Aborts an ongoing operation. The URL is http://:/ solr/ / dataimport? command=abort.
For incremental imports and change detection. The command is of the form http://:/ solr/ / dataimport? command=delta-impor
t. It supports the same clean, commit, optimize and debug parameters as full-import
command. Only the SqlEntityProcessor supports delta imports.
