We use the plugin “WooCommerce Ajax Filter’ to have some filters on attributes. Apparently they use the Lookup Table.
Recently the filters weren’t working that good, not all products were shown. After regenerating the Lookup Table, the filters were working again.
The question is now: is there an indication when to regenerate it again? Also core WooCommerce uses that Lookup table, but it’s not clear to me when to run it again cause it’s not always obvious to see those filter issues.
