DROP SEARCH INDEX

Drops a Solr-based DSE Search index from a table and optionally deleted the resources associated with the search index.

Restriction: Command available only on DSE Search nodes. Running search index management commands on large datasets can take longer than the CQLSH default timeout of 10 minutes. Increase the CQLSH client timeout as required.

To drop a Storage-Attached Indexing (SAI) index, use DROP INDEX.

Synopsis

DROP SEARCH INDEX ON [<keyspace_name>.]<table_name>
  OPTIONS { <option> : <value> } [ , { <option> : <value> } ... ] ;

Syntax legend

Legend
Syntax conventions	Description
UPPERCASE	Literal keyword.
Lowercase	Not literal.
`< >`	Variable value. Replace with a 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.
`<datatype2`	Set, list, map, or tuple. Angle brackets ( `< >` ) enclose data types in a set, list, map, or tuple. Separate the data types with a comma.
`<cql_statement>;`	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.
`@<xml_entity>='<xml_entity_type>'`	Search CQL only: Identify the entity and literal value to overwrite the XML element in the schema and solrConfig files.

EBNF

EBNF syntax:

dropSearchIndex   ::= 'DROP' 'SEARCH' 'INDEX'
                      'ON' tableName
                      ('WITH' 'OPTIONS' optionMap)?
tableName         ::= (keyspace '.')? table
optionMap         ::= '{' (key ':' value (',' key ':' value)*)? '}'

The request options are boolean values:

deleteResources

true - deletes the resources associated with the search index.
false - does not delete the resources. Default: true

deleteDataDir

true - deletes index data and any other artifacts in the solr.data directory. It does not delete data from the database.
false - does not delete index data. Default: false

Examples

The search index is dropped for the wiki.solr keyspace and table, and the specified options.

Delete the resources associated with the search index

DROP SEARCH INDEX ON wiki.solr;

Keep the resources associated with the search index

DROP SEARCH INDEX ON wiki.solr WITH OPTIONS { deleteResources:false };
