!!! note

When using the variable `e` to match fixed-length or variable-length paths in a pattern, such as `-[e:follow*0..3]->`, it is not supported to reference `e` in other patterns. For example, the following statement is not supported.

```ngql
nebula> MATCH (v:player)-[e:like*1..3]->(n) \
WHERE (n)-[e*1..4]->(:player) \
RETURN v;
```

### Match variable-length paths with multiple edge types

You can specify multiple edge types in a fixed-length or variable-length pattern. In this case, `hop`, `minHop`, and `maxHop` take effect on all edge types.
