The solrconfig. xml file is located in the conf/ directory for each collection. Several well-commented example files can be found in the server/solr/configsets/ directories demonstrating best practices for many different types of installations.
The Solr schema. xml (typically found in the solr/conf/ directory) is where you tell Solr what types of fields you plan to support, how those types will be analyzed, and what fields you are going to make available for import and queries. Solr will then base its Lucene underbelly on what you define.
Any core. properties file in any directory of your Solr installation (or in a directory under where solr_home is defined) will be found by Solr and the defined properties will be used for the core named in the file. In standalone mode, solr. xml must reside in solr_home .
As it is mentionned in the wiki that you referenced in the link , instanceDir parameter in the http request is a required parameter. config, schema & dataDir parameters are optional. (Default is to look for solrconfig.xml/schema.xml inside instanceDir. Default place to look for dataDir depends on solrconfig.xml.) Example of Create Request
http://localhost:8983/solr/admin/cores?action=CREATE&name=coreX&instanceDir=path_to_instance_directory&
config=config_file_name.xml&schema=schema_file_name.xml&dataDir=data
