Parent products excluding children_attributes

[JamesAllwood]

At the moment, this is a question, not a bug.

Tested on Magento 2.3.2 and ES 2.8.1

I noticed that in one site running elasticsuite, the results in the layered navigation didn't seem correct. For example, on a particular category, there should have been around 10 results for the colour Orange.

After investigation, I looked in to the data store in elasticsearch, and could see that for the configurable product in question, it included no records for children_attributes.

"children_attributes" : [
            "indexed_attributes"
          ],

However, it did have children_ids

          "children_ids" : [
            131036,
            131037,
            131038
          ],

So, I debugged this by moving the data to a vanilla install and testing again. Same result.

I then created a new configurable product, assigning the same children, and this time, the new product included the children_attributes, but the original configurable product remained with these missing.

New product data:

          "children_ids" : [
            131036,
            131037,
            131038
          ],
          "children_attributes" : [
            "image",
            "description",
            "short_description",
            "brand",
            "option_text_brand",
            "guarantee",
            "option_text_guarantee",
            "lead_time",
            "option_text_lead_time",
            "search_colour",
            "option_text_search_colour",
            "height_adjustable",
            "option_text_height_adjustable",
            "seat_fabric",
            "option_text_seat_fabric",
            "indexed_attributes"
          ],

Old product data:

          "children_ids" : [
            131036,
            131037,
            131038
          ],
          "children_attributes" : [
            "indexed_attributes"
          ],

So, this confirms it's data related. I've checked for relationship differences, and there is nothing that I can find.

Just wondering if anyone has had similar experience, or any ideas what might be responsible

I figured this out in the end. It seems that if the parent item has a value for an attribute, ES does not include the values of the child in the children_attributes. So, if you're also experiencing this issue, just remove the value from the configurable product, and it should all work correctly.

I'm not sure if this is a bug or intentional? Certainly the default layered navigation doesn't work in the same way, so I'm inclined to think it may be a bug.

Sorry for the delay on this one, but if I understand correctly, we are not merging children data into the parent data when indexing, if parent product has a value for an attribute that also exists on its children.

Or maybe we do override the children value by the parent value later in the indexing process.

@androshchuk and @serg6854 can you try to reproduce this one and to provide a fix ?
