What is File Management?
To enable various file operations via the browser, KandaSearch provides the 'File Manager' feature.
It's very convenient as it allows access to various files without requiring special settings or specialized knowledge like SSH or FTP.
File management is done on a per-Apache Solr instance (*1) node basis. In SolrCloud configuration, which consists of multiple nodes, the file management screen will display a combo box for node selection, allowing you to select the target node for operation.
*1: In KandaSearch, whether it's a standalone Solr or a SolrCloud, both are referred to as 'A Solr instance'.
In File Management, you can access folders and files under the /solr folder prepared on a per-Apache Solr node basis.
When downloading backup data, files downloaded by selecting 'DOWNLOAD TO CLOUD' can be found under _restore under the /solr folder.
Please note that due to administrative reasons in KandaSearch, some files may not be displayed or editable.
For example: /solr/log4j2.xml in the Community plan is hidden.
To use File Management
To utilize File Management, follow these steps to display the File Management screen:
