The Solr Configuration REST API lets you access and manage Solr configuration files stored in ZooKeeper. To manage Solr lists of stopwords, see Stopwords Files. For more information, view the API specification.

Solr Configuration Definition Properties

Path Parameters
ParameterDescription
collectionThe collection that contains the configuration files to list or view.
pathThe path to a specific file or nested child nodes. If the file is not nested, the filename can be entered without any path information.
Query Parameters
ParameterDescription
expandIf true, the binary content of a file will be returned base64 encoded. If this is not included, only the metadata about each node will be returned. If you would like to see the content of the file in plain text, you can add ‘Accept: text/plain’ to the request header. Alternately, you can get the raw bytes by adding ‘Accept: application/octet-stream’ to the header.
recursiveIf true, children of nested ZooKeeper nodes will be returned. This can be used in conjunction with the path to show only children of a specific node.
The output will include a list of each file with the following information:
  • name. The name of the file or node.
  • version. The file or node version from ZooKeeper.
  • isDir. If the node has children, this value will be true.
  • value. Only returned if “expand=true” is added as a query parameter. This will be returned as the base64 encoding of the contents of the file.
If the header includes ‘Accept: text/plain’ or ‘Accept: application/octet-stream’, metadata about the file will not be returned and only the content as either plain text or raw bytes. If recursive=true and expand=true are both used in the same request, the request may be a little slow depending on how much data is requested.

ZooKeeper Collection Configuration Definition Properties

Path Parameters
ParameterDescription
collectionThe collection that contains the configuration files to list or view.
pathThe path to a specific file (including nested child nodes).
Query Parameters
ParameterDescription
reloadIf true, the collection will be reloaded to make the changes available to Solr immediately.
Input Content The REST API does not restrict the type of content that can be sent to ZooKeeper, but care should be taken to make sure the format of the file remains compatible with Solr’s requirements. As a best practice, all requests should include the Content-type in the request header.

Examples

Show _rest_managed.json for the ‘docs’ collection, with the base64 encoded content: INPUT 
curl -u USERNAME:PASSWORD https://FUSION_HOST:FUSION_PORT/api/collections/docs/solr-config/_rest_managed.json?expand=true
OUTPUT 
{
  "name" : "_rest_managed.json",
  "version" : 0,
  "isDir" : false,
  "value" : "eyJpbml0QXJncyI6e30sIm1hbmFnZWRMaXN0IjpbXX0NCg=="
}
Get the plain text version of ‘synonyms.txt’: INPUT 
curl -u USERNAME:PASSWORD -H 'Accept: text/plain' https://FUSION_HOST:FUSION_PORT/api/collections/docs/solr-config/synonyms.txt
OUTPUT 
GB,gib,gigabyte,gigabytes
MB,mib,megabyte,megabytes
Television, Televisions, TV, TVs
pixima => pixma
Show the child nodes of ‘clustering’: INPUT 
curl -u USERNAME:PASSWORD https://FUSION_HOST:FUSION_PORT/api/collections/docs/solr-config/clustering?recursive=true
OUTPUT 
{
  "name" : "clustering",
  "version" : 0,
  "isDir" : true,
  "children" : [ {
    "name" : "carrot2",
    "parent" : "clustering",
    "version" : 0,
    "isDir" : true,
    "children" : [ {
      "name" : "kmeans-attributes.xml",
      "parent" : "clustering/carrot2",
      "version" : 0,
      "isDir" : false
    }, {
      "name" : "lingo-attributes.xml",
      "parent" : "clustering/carrot2",
      "version" : 0,
      "isDir" : false
    }, {
      "name" : "stc-attributes.xml",
      "parent" : "clustering/carrot2",
      "version" : 0,
      "isDir" : false
    } ]
  } ]
}
Replace the contents of the existing synonyms.txt file with the contents of a file named “updated-synonyms.txt” and reload the collection: INPUT 
curl -u USERNAME:PASSWORD -X PUT -H 'Content-type: text/plain' --data-binary'@updated-synonyms.txt' https://FUSION_HOST:FUSION_PORT/api/collections/docs/solr-config/synonyms.txt?reload=true
OUTPUT None.
