示例Graph
您可以先运行SHOW TAG INDEXES查看有哪些标签索引，然后用SHOW CREATE TAG INDEX查看指定索引的创建信息。
nebula> SHOW TAG INDEXES;
+------------------+
| Names |
+------------------+
| "player_index_0" |
+------------------+
| "player_index_1" |
+------------------+
nebula> SHOW CREATE TAG INDEX player_index_1;
+------------------+--------------------------------------------------+
| Tag Index Name | Create Tag Index |
+------------------+--------------------------------------------------+
| "player_index_1" | "CREATE TAG INDEX `player_index_1` ON `player` ( |
| | `name(20)` |
| | )" |
+------------------+--------------------------------------------------+
边类型索引可以用类似的方法查询：
nebula> SHOW EDGE INDEXES;
+----------------+
| Names |
+----------------+
| "index_follow" |
+----------------+
nebula> SHOW CREATE EDGE INDEX index index_follow;
+-----------------+-------------------------------------------------+
| Edge Index Name | Create Edge Index |
+-----------------+-------------------------------------------------+
| "index_follow" | "CREATE EDGE INDEX `index_follow` ON `follow` ( |
| | `degree` |
| | )" |
+-----------------+-------------------------------------------------+
