Our Magento store has a lot of products. We have one multiselect attribute with a lot of options (values). All products has these attribute and also multiple values selected per product.
But on category page under filters (layered nav), these multiselect attribute dosen't display all products. All options of these attribute if selected display less products than it should be.
All indexes are ok and cache also.
I was reading that multiselect attribute is "varchar" and because of that you can save more then 255 options.
Sorry for the bump, but is quite annoying these issue for us.
Does anyone have any idea how to fix that in Magento?
