Ni,

I am trying to get an exclude filter working.  
I am a bit unfamiliar with the ways the queries are built but I used the tags query already existing and used MustNot instead of Should (see below)

Issue is that if it matches on 1 variant of many on a product it will exclude that product. I only want it to remove said variant from result. If all variants are matched then it wont display the product on the category page.

Currently testing with a TextOption field where you can set different values in BO and based on that filter it out if needed.

Any ideas what could be wrong? Also thanks in advance.

```auto
                if (excludeTags != null)
                {
                    foreach (var excludeTag in excludeTags.Where(x => x.Value.Count > 0))
                    {
                        var filterTags = excludeTag.Value
                            .Select<string, Func<QueryContainerDescriptor<ProductDocument>, QueryContainer>>(tagValue =>
                                s => s
                                    .Nested(n => n
                                        .Path(x => x.Tags)
                                        .Query(nq
                                            => nq.Term(t => t.Field(f => f.Tags[0].Key).Value(excludeTag.Key))
                                               && nq.Term(t => t.Field(f => f.Tags[0].Value).Value(tagValue))
                                        )
                                    ));
                        allQueries.Add(qc.Bool(b => b.Filter(bf => bf.Bool(bb => bb.MustNot(filterTags)))));
                    }
                }

```
