I am trying to do a search using QueryOver however the results returned, although are right based on the search criteria, are being duplicated.
Here is the code I am using to count the results, which works correctly
// 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();
If I change the last line to a select statement with skip and take like so
return returned.OrderBy(x => x.CreatedUTC).Desc.Skip(skip).Take(take).List<Note>();
Then I get the 3 notes back, instead of 2. 1 note is duplicated, while the other is ok. I can only assume that is because the query matched two of the tags linked to one note.
The SQL outputted by nHibernate profiler is as follows

WHERE (this_0_0_.CreatedUTC >= '2012-06-01T00:00:00.00' /* @p1 */
and this_0_0_.CreatedUTC <= '2012-06-30T00:00:00.00' /* @p2 */)
and (lower(this_0_0_.Text) like '%dtes%' /* @p3 */
or this_0_0_.Id in (SELECT this_0_0_0_.Id as y0_

on tags3_.TagId = tag1_.Id
WHERE lower(tag1_.Text) like '%dtes%' /* @p4 */)))
and account1_.CompanyId = 1 /* @p5 */)
ORDER BY this_.CreatedUTC desc
If I put this directly into SQL management studio it returns 3 results, two of which are the same.
