我正在尝试使用 QueryOver 进行搜索，但是返回的结果虽然根据搜索条件是正确的，但正在重复。
这是我用来计算结果的代码，它可以正常工作
// disjunction to find query string in note text of tag list
var disjunction = new Disjunction();
disjunction.Add(Restrictions.On<Note>(e => e.Text).IsInsensitiveLike(query));
var tagSubQuery = QueryOver.Of<Note>().JoinQueryOver(x => x.Tags).Where(x => x.Text.IsInsensitiveLike(query)).Select(x => x.Id);
disjunction.Add(Subqueries.WhereProperty<Note>(x => x.Id).In(tagSubQuery));
// find notes between dates and based on disjunction
var notes = this.DataOver.Where(x => x.CreatedUTC >= startDate && x.CreatedUTC <= endDate).Where(disjunction);
// only show notes within permitted accounts
var subnotes = QueryOver.Of<Note>().JoinQueryOver(x => x.Accounts).Where(x => x.Company.Id == user.Company.Id).Select(x => x.Id);
var returned = notes.WithSubquery.WhereProperty(x => x.Id).In(subnotes);
return returned.RowCount();
如果我将最后一行更改为带有跳过的选择语句并采取这样的方式
return returned.OrderBy(x => x.CreatedUTC).Desc.Skip(skip).Take(take).List<Note>();
然后我拿回 3 个音符，而不是 2 个。1 个音符被复制，而另一个没问题。我只能假设这是因为查询匹配了链接到一个笔记的两个标签。
nHibernate profiler输出的SQL如下

如果我将它直接放入 SQL 管理工作室，它会返回 3 个结果，其中两个是相同的。
