| 匹配边的属性 | ` MATCH (v:player{name:"Tim Duncan"})-[e:follow{degree:95}]->(v2) RETURN e` | 用户可以用`{<prop_name>: <prop_value>}`表示模式中 Edge type 的属性，例如`[e:follow{likeness:95}]`。 |
| 匹配多个 Edge type | `MATCH (v:player{name:"Tim Duncan"})-[e:follow | :serve]->(v2) RETURN e` | 使用`|`可以匹配多个 Edge type，例如`[e:follow | :serve]`。第一个 Edge type 前的英文冒号（:）不可省略，后续 Edge type 前的英文冒号可以省略，例如`[e:follow | serve]`。 |
| 匹配多条边 | `MATCH (v:player{name:"Tim Duncan"})-[]->(v2)<-[e:serve]-(v3) RETURN v2, v3` | 用户可以扩展模式，匹配路径中的多条边。 |
| 匹配定长路径 | `MATCH p=(v:player{name:"Tim Duncan"})-[e:follow*2]->(v2) RETURN DISTINCT v2 AS Friends` | 用户可以在模式中使用`:<edge_type>*<hop>`匹配定长路径。`hop`必须是一个非负整数。 |
| 匹配变长路径 | `MATCH p=(v:player{name:"Tim Duncan"})-[e:follow*1..3]->(v2) RETURN v2 AS Friends` | `minHop`：可选项。表示路径的最小长度。`minHop`必须是一个非负整数，默认值为 1。<br>`maxHop`：必选项。表示路径的最大长度。`maxHop`必须是一个非负整数，没有默认值。 |
| 匹配多个 Edge type 的变长路径 | `MATCH p=(v:player{name:"Tim Duncan"})-[e:follow | serve*2]->(v2) RETURN DISTINCT v2` | 用户可以在变长或定长模式中指定多个 Edge type。`hop`、`minHop`和`maxHop`对所有 Edge type 都生效。 |
| 匹配定长路径 | `MATCH p=(v:player{name:"Tim Duncan"})-[e:follow*2]->(v2) RETURN DISTINCT v2 AS Friends` | 用户可以在模式中使用`:<edge_type>*<hop>`匹配定长路径。`hop`必须是一个非负整数。`e`的数据类型是列表。 |
| 匹配变长路径 | `MATCH p=(v:player{name:"Tim Duncan"})-[e:follow*1..3]->(v2) RETURN v2 AS Friends` | `minHop`：可选项。表示路径的最小长度。`minHop`必须是一个非负整数，默认值为 1。<br>`maxHop`：必选项。表示路径的最大长度。`maxHop`必须是一个非负整数，没有默认值。`e`的数据类型是列表。 |

| 检索点或边的信息 | `MATCH (v:player{name:"Tim Duncan"}) RETURN v`<br>`MATCH (v:player{name:"Tim Duncan"})-[e]->(v2) RETURN e` | 使用`RETURN {<vertex_name> | <edge_name>}`检索点或边的所有信息。 |
| 检索点 ID | `MATCH (v:player{name:"Tim Duncan"}) RETURN id(v)` | 使用`id()`函数检索点 ID。 |
| 检索 Tag | `MATCH (v:player{name:"Tim Duncan"}) RETURN labels(v)` | 使用`labels()`函数检索点上的 Tag 列表。<br>检索列表`labels(v)`中的第 N 个元素，可以使用`labels(v)[n-1]`。 |
