Since updating to 0.47, I can no longer search with a BigQuery table name and have Metabase return all the questions that use the table I searched. Also, when I go to the "references" page in the UI, I get no results for "questions about this table".
Here is a better example where the table is used in 60 questions but Metabase doesn't return one.
mysql> SELECT count(*) FROM report_card WHERE dataset_query LIKE "%general_xxxxx_staff%";
+----------+
| count(*) |
+----------+
| 60 |
+----------+
1 row in set (0.10 sec)
