I use feed in the form of CSV. Particular product in my Catalog search looks like this:  Sample row with values looks like this:## RECSentity.id,entity.sku,entity.pageUrl,entity.name,entity.thumbnailUrl,entity.categoryId,entity.message,entity.value,entity.inventory,entity.margin,entity.last_updated_...

My case is:1. Removed all the old Feeds.2. Added new feed with entity.custom1 , entity.custom2 attributes3. Feed uploaded with success4. When I go through products in Catalog Search I do not see new custom entities... It looks like that Catalog Search is based on old FeedsWhat should I do next after...
