function commerce_backoffice_handler_filter_term_node_tid::query in Commerce Backoffice 7

Add this filter to the query.

Due to the nature of fapi, the value and the operator have an unintended level of indirection. You will find them in $this->operator and $this->value respectively.

Overrides views_handler_filter::query
