Italic, bold, or < >

Syntax diagrams and code samples use one or more of these styles to mark placeholders for variable values. Replace placeholders with a valid option or your own user-defined value.

In CQL statements, angle brackets are required to enclose data types in a set, list, map, or tuple. Separate the data types with a comma. For example: <datatype2

In Search CQL statements, angle brackets are used to identify the entity and literal value to overwrite the XML element in the schema and solrconfig files, such as @<xml_entity>='<xml_entity_type>'.

[ ]

Square brackets surround optional command arguments. Do not type the square brackets.

( )

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

|

A pipe separates alternative elements. Type any one of the elements. Do not type the pipe.

...

Indicates that you can repeat the syntax element as often as required.

'

Single quotation marks must surround literal strings in CQL statements. Use single quotation marks to preserve upper case. + For Search CQL only: Single quotation marks surround an entire XML schema declaration, such as '<<schema> ... </schema>>'

{ }

Map collection. Curly braces enclose maps ({ <key_datatype>:<value_datatype> }) or key value pairs ({ <key>:<value> }). A colon separates the key and the value.

;

Ends a CQL statement.

--

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