Trying to make a bug report out of bug 23204##40 Note : Since bug 20589, two fields have been added to 'search_field' table: staff_client and opac. Those fields are lacking in mappings.yaml. Its means that if this script is used to export and import (Reset mapping in Search engine configuration) indexing rules, the searchability (staff/opac) of fields will be lost.
