Core-Specific Tools

The Core-Specific tools are a group of UI screens that allow you to see core-level information.

In the left-hand navigation bar, you will see a pull-down menu titled "Core Selector". Clicking on the menu will show a list of Solr cores hosted on this Solr node, with a search box that can be used to find a specific core by name.

When you select a core from the pull-down, the main display of the page will show some basic metadata about the core, and a secondary menu will appear in the left nav with links to additional core specific administration screens.

You can also define a configuration file called admin-extra.html that includes links or other information you would like to display in the "Admin Extra" part of this main screen.

  • Ping - lets you ping a named core and determine whether the core is active.

  • Plugins/Stats - shows statistics for plugins and other installed components.

  • Replication - shows you the current replication status for the core, and lets you enable/disable replication.

  • Files - shows the current core configuration files such as solrconfig.xml.

  • Query - lets you submit a structured query about various elements of a core.

  • Stream - allows you to submit streaming expressions and see results and parsing explanations.
