Info

Configuring the Admin UI in solrconfig.xml You can configure the Solr Admin UI by editing the file solrconfig.xml. The 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. solr Related Topics Configuring solrconfig.xml Getting Assistance At the bottom of each screen of the Admin UI is a set of links that can be used to get more assistance with configuring and using Solr. Assistance icons These icons include the following links. Link Description Documentation Navigates to the Apache Solr documentation hosted on http://lucene.apache.org/solr/ . Issue Tracker Navigates to the JIRA issue tracking server for the Apache Solr project. This server resides at http://issues.apache.org/jira/br owse/SOLR. IRC Channel Connects you to the web interface for Solr's IRC channel. This channel is found on Irc.freenode.net, Port 7000, #solr channel. Community forum Solr Query Syntax Connects you to the Solr community forum, which at the current time is a set of mailing lists and their archives. Navigates to the Apache Wiki page describing the Solr query syntax: http://wiki.apache.org/solr/SolrQuerySyntax. These links cannot be modified without editing the admin.html in the solr.war that contains the Admin UI files. Logging The Logging page shows messages from Solr's log files. When you click the link for "Logging", a page similar to the one below will be displayed: Apache Solr Reference Guide 4.6 14
The Main Logging Screen While this example shows logged messages for only one core, if you have multiple cores in a single instance, they will each be listed, with the level for each. Selecting a Logging Level When you select the Level link on the left, you see the hierarchy of classpaths and classnames for your instance. A row highlighted in yellow indicates that the class has logging capabilities. Click on a highlighted row, and a menu will appear to allow you to change the log level for that class. Characters in boldface indicate that the class will not be affected by level changes to root. For an explanation of the various logging levels, see Configu ring Logging. Cloud Screens When running in SolrCloud mode, an option will appear in the Admin UI between Logging and Core Admin for Cloud. It's not possible at the current time to manage the nodes of the SolrCloud cluster, but you can view them and open the Solr Admin UI on each node to view the status and statistics for the node and each core on each node. Click on the Cloud option in the left-hand navigation, and a small sub-menu appears with options called "Tree", "Graph", "Graph (Radial)" and "Dump". The default view (which is "Tree") shows a graph of each core and the addresses of each node. This example shows a very simple two-node cluster with a single core: Apache Solr Reference Guide 4.6 15
