NHIBERNATE WHERE and Multiple OR clause of IQUERYOVER - c#-4.0

Question

Hi: I tried looking at other posts. I apologize in advance if this is a duplicate post.
The sql query is something like this:
select * from ApiData where BrandID = 'SOUPBRAND' and Culture = 'de-de'
or
( BrandID = 'SOUPBRAND' and Culture = 'pt-br' and EntityType = 'contactus')
or
(BrandID = 'examplefoods')
What would the nhibernate query look like?
This is what I have so far:
var mainQuery = _session.QueryOver<ApiData>();
foreach (var brandPermission in permissions)
{
var query = _session.QueryOver<ApiData>();
if (!string.IsNullOrEmpty(brandPermission.Culture) && !string.IsNullOrEmpty(brandPermission.Publication))
{
query = query.Where(a => (a.Culture == brandPermission.Culture)
&& (a.Publication == brandPermission.Publication)); //FetchEntries(apiUser.DefaultCulture, apiUser.Publication);
}
else if (!string.IsNullOrEmpty(brandPermission.Culture))
{
query = query.Where(a => (a.Culture == brandPermission.Culture)); //FetchEntries(apiUser.DefaultCulture);
}
query = query.Where(a => a.BrandId == brandPermission.BrandId);
//Here I would like to add
// mainQuery.AddORRestriction(query);
}
Just dont know how to achieve it. Saw a link :http://www.methodicmadness.com/2012/04/extending-queryover-with-or.html but didnt help.
Thanks!

I got the following solution:
var mainQuery = _session.QueryOver<ApiData>();
var holdOr = Restrictions.Disjunction();
foreach (var brandPermission in permissions)
{
var query = _session.QueryOver<ApiData>();
var holdAnd = Restrictions.Conjunction();
if (!string.IsNullOrEmpty(brandPermission.Culture) && !string.IsNullOrEmpty(brandPermission.Publication))
{
holdAnd.Add(Restrictions.Eq("Culture", brandPermission.Culture));
holdAnd.Add(Restrictions.Eq("Publication", brandPermission.Publication));
}
else if (!string.IsNullOrEmpty(brandPermission.Culture))
{
holdAnd.Add(Restrictions.Eq("Culture", brandPermission.Culture));
}
holdAnd.Add(Restrictions.Eq("BrandId", brandPermission.BrandId));
holdOr.Add(holdAnd);
}
mainQuery.Where(holdOr);
