如何使用Lucene API（a AND（b OR c））创建嵌套的布尔查询？

我认为将是这样的：

TermQuery userQuery = new TermQuery(new Term("user_id", u.getId()+""));BooleanQuery orQuery = new BooleanQuery();orQuery.add(new BooleanClause(name_query, Occur.SHOULD));orQuery.add(new BooleanClause(desc_query, Occur.SHOULD));BooleanQuery andQuery = new BooleanQuery();andQuery.add(new BooleanClause(userQuery , Occur.MUST));andQuery.add(new BooleanClause(orQuery, Occur.MUST));
