Solr features a Web interface that makes it easy for Solr administrators and programmers to view Solr configuration details, run queries and analyze document fields in order to fine-tune a Solr configuration and access online documentation and other help.
With Solr 4, the Solr Admin has been completely redesigned. The redesign was completed with these benefits in mind:
- load pages quicker
- access and control functionality from the Dashboard
- re-use the same servlets that access Solr-related data from an external interface, and
- ignore any differences between working with one or multiple cores.
Accessing the URL http://hostname:8983/solr/admin/ (if running Jetty on the default port of 8983), will show the main dashboard, which is divided into two parts.
A left-side of the screen is a menu under the Solr logo that provides the navigation through the screens of the UI. The first set of links are for system-level information and configuration and provide access to Logging, Core Admin and Java Properties, among other things. At the end of this information is a list of Solr cores configured for this instance. Clicking on a core name shows a secondary menu of information and configuration options for the core specifically. Items in this list include the Schema, Config, Plugins, and an ability to perform Queries on indexed data.
The center of the screen shows the detail of the option selected. This may include a sub-navigation for the option or text or graphical representation of the requested data. See the sections in this guide for each screen for more details.
|If you are running Solr on a Macintosh, you should access the Admin UI in a browser other than Safari, because Safari will not display raw XML content, such as the contents of the schema.xml file.|
You can configure the Solr Admin UI by editing the file solrconfig.xml.
The <admin> block in the solrconfig.xml file determines the default query to be displayed in the Query section of the core-specific pages. The default is *:*, which is to find all documents. In this example, we have changed the default to the term solr.
