Create search_index_0 to search_index_15 tables and shard each index by account id. MySQL has no ability to pre-filter fulltext indexes by another field so this is the best bet for improving performance. Each fulltest index internally creates 11 sub tables (see https://dev.mysql.com/doc/refman/8.4/en/innodb-fulltext-index.html) so actually we have 192 tables in total here. The search_index table name is generated dynamically based on the account_id.
