Hi Adrian

Score is Lucene scoring - which is impossible to understand exactly how works. When you only have one parameter, groupid, you probably get the same lucene score for all documents, and then the order will be something 'random' - maybe document order in Lucene - lucene handles all that.

When using "Use group sorting" the index will try to sort products by its groupid looking at some dw built in fields in the index - but since your products are in subgroups and their sorting value comes from the subgroups, it will not have affect on parent group searches with no products in them.

If you use group sorting, each product in each subgroup has a sort value - so if you have 3 subgroups, the first product in all groups will have the same sort value - 1.

So to do what you want, you need to create a combined sorting field you can use for this scenario - a combination of subgroup sorting value and product sorting value and put it in a new field.

Hi Nicolai,

Thank you. Sounds like a good plan.

In the meantime I have added 2 sorting criteria. First by ParentGroupId and then by score.

Of course, this is working now becuase I have defined the GroupIds consistently and will probably break (or not sorting properly) once the groups will be defined randomly.

I will try to add this combined field as it seems to be more reliable on the loing run.

Thank you,
Adrian
