dsetool unload_core

Removes a search index. Supports DSE authentication with [-l <username> -p <password>].

To drop a search index from a table and delete all related data for the entire cluster, see DROP SEARCH INDEX.

The removal of the secondary index from the table schema is always distributed.

Restriction: Command is supported only on nodes with DSE Search workloads.

Syntax conventions Description


Literal keyword.


Not literal.


Variable value. Replace with a valid option or user-defined value.

[ ]

Optional. Square brackets ( [ ] ) surround optional command arguments. Do not type the square brackets.

( )

Group. Parentheses ( ( ) ) identify a group to choose from. Do not type the parentheses.


Or. A vertical bar ( | ) separates alternative elements. Type any one of the elements. Do not type the vertical bar.


Repeatable. An ellipsis ( ... ) indicates that you can repeat the syntax element as often as required.

'<Literal string>'

Single quotation ( ' ) marks must surround literal strings in CQL statements. Use single quotation marks to preserve upper case.

{ <key>:<value> }

Map collection. Braces ( { } ) enclose map collections or key value pairs. A colon separates the key and the value.


Set, list, map, or tuple. Angle brackets ( < > ) enclose data types in a set, list, map, or tuple. Separate the data types with a comma.


End CQL statement. A semicolon ( ; ) terminates all CQL statements.

[ -- ]

Separate the command line options from the command arguments with two hyphens ( -- ). This syntax is useful when arguments might be mistaken for command line options.

' <<schema> ... </schema> >'

Search CQL only: Single quotation marks ( ' ) surround an entire XML schema declaration.


Search CQL only: Identify the entity and literal value to overwrite the XML element in the schema and solrconfig files.

deleteDataDir=( true | false )

Whether to delete index data and any other artifacts in the solr.data directory.

Valid values:

  • true - Deletes index data and any other artifacts in the solr.data directory. It does not delete DataStax Enterprise data.

  • false - Default. Does not delete index data or other artifacts.

deleteResources=( true | false )

Whether to delete the config and schema resources associated with the search index.

Valid values:

  • true - Deletes index resources.

  • false - Default. Does not delete index resources.


Whether to distribute and apply the operation to all nodes in the local datacenter.

  • True applies the operation to all nodes in the local datacenter.

  • False applies the operation only to the node it was sent to. False works only when recovery=true.

Default: true

Distributing a re-index to an entire datacenter degrades performance severely in that datacenter.
