### Match shortest paths

The `allShortestPaths` function can be used to find all shortest paths between two vertices.

```
nebula> MATCH p = allShortestPaths((a:player{name:"Tim Duncan"})-[e*..5]-(b:player{name:"Tony Parker"})) \
RETURN p;
+------------------------------------------------------------------------------------------------------------------------------------+
| p |
+------------------------------------------------------------------------------------------------------------------------------------+
| <("player100" :player{age: 42, name: "Tim Duncan"})<-[:follow@0 {degree: 95}]-("player101" :player{age: 36, name: "Tony Parker"})> |
| <("player100" :player{age: 42, name: "Tim Duncan"})-[:follow@0 {degree: 95}]->("player101" :player{age: 36, name: "Tony Parker"})> |
+------------------------------------------------------------------------------------------------------------------------------------+
```

The `shortestPath` function can be used to find a single shortest path between two vertices.


```
nebula> MATCH p = shortestPath((a:player{name:"Tim Duncan"})-[e*..5]-(b:player{name:"Tony Parker"})) \
RETURN p;
+------------------------------------------------------------------------------------------------------------------------------------+
| p |
+------------------------------------------------------------------------------------------------------------------------------------+
| <("player100" :player{age: 42, name: "Tim Duncan"})<-[:follow@0 {degree: 95}]-("player101" :player{age: 36, name: "Tony Parker"})> |
+------------------------------------------------------------------------------------------------------------------------------------+
```
