Simple (E1 AND E2) OR (E3 AND E4) expression in QueryDSL

Question

How do I express in QueryDSL where clause in form: ``` WHERE (E1 AND E2) OR (E3 AND E4) ``` E1..E4 are arbitrary boolean expressions. The point is to have a query started within parenthesis, thus (E1 AND E2).

Accepted Answer

```
where(e1.and(e2).or(e3.and(e4)))
```
