A function inserts into that table:

		insert into dataset_search (column_id, type, full_label, description, data_source_description, name, display_name, short_label, link, taxonomy_terms, product_ids, group_ids, all_words, search) values
			(_id, _type, full_label, description, data_source_description, name, display_name, short_label, link, taxonomy_terms, product_ids, group_ids,
