|`TAG \| EDGE`| 指定要创建的索引类型。|
|`IF NOT EXISTS`|检测待创建的索引是否存在，只有不存在时，才会创建索引。|
|`<index_name>`|索引名。索引名在一个图空间中必须是唯一的。推荐的命名方式为`i_tagName_propName`。索引名称以英文字母开头，支持 1~4 字节的 UTF-8 编码字符，包括英文字母（区分大小写）、数字、中文等，但是不包括除下划线外的特殊字符。使用特殊字符或保留关键字时，需要用反引号（\`）包围，详情参见[关键字和保留字](../../3.ngql-guide/1.nGQL-overview/keywords-and-reserved-words.md)。|
|`<tag_name> \| <edge_name>`|指定索引关联的 Tag 或 Edge 名称。|
|`<tag_name> | <edge_name>`|指定索引关联的 Tag 或 Edge 名称。|
|`<prop_name_list>`|为**变长**字符串属性创建索引时，必须用`prop_name(length)`指定索引长度；为 Tag 或 Edge type 本身创建索引时，忽略`<prop_name_list>`。|
|`COMMENT`|索引的描述。最大为 256 字节。默认无描述。|
