遍历多个Edge type时，`WHERE`子句有一些限制。例如不支持`WHERE edge1.prop1 > edge2.prop2`。

- `YIELD [DISTINCT] <return_list>`：定义需要返回的输出。` <return_list>`建议使用[Schema函数](../6.functions-and-expressions/4.schema.md)，当前支持`src(edge)`、`dst(edge)`、`type(edge)`、`rank(edge)`、`properties(edge)`、`id(vertex)`、`properties(vertex)`。详情请参见[YIELD](../8.clauses-and-options/yield.md)。如果没有指定，默认返回目的点ID。
- `YIELD [DISTINCT] <return_list>`：定义需要返回的输出。` <return_list>`建议使用[Schema函数](../6.functions-and-expressions/4.schema.md)，当前支持`src(edge)`、`dst(edge)`、`type(edge)`、`rank(edge)`、`properties(edge)`、`id(vertex)`、`properties(vertex)`，暂不支持嵌套函数。详情请参见[YIELD](../8.clauses-and-options/yield.md)。如果没有指定，默认返回目的点ID。

- `GROUP BY`：根据指定属性的值将输出分组。详情请参见[GROUP BY](../8.clauses-and-options/group-by.md)。分组后需要再次使用`YIELD`定义需要返回的输出。
