Troubleshooting and todo in the future

When change root category of virtual category, previous products still are in the category

To remove product from categories run full reindexation.

After turn on module, virtual category does not display products anymore

If you see products on the preview in admin area:

it seems that ES is able to return the right product IDs in the indexer.

Make sure that the script provides the right category object here:

vendor/creativestyle/magesuite-elasticsuite-virtual-category-indexer/Model/Indexer/VirtualCategoryIndexer.php:150

should be the same as here:

vendor/creativestyle/magesuite-elasticsuite-virtual-category-indexer/Controller/Adminhtml/Category/Virtual/Preview.php:67
