INDEX_STATISTICS does not show data for FULLTEXT indexes

Details

    Description

      FULLTEXT indexes are not included into INDEX_STATISTICS. Maybe it's intentional, in which case it needs to be reflected in the documentation (if it hasn't been yet).

      SET @userstat.save= @@userstat;
      		 
      set global userstat= 1;
      		 
       
      		 
      create table ft (c text,fulltext(c));
      		 
      insert into ft (c) values ('Once upon a time'),
      		 
        ('There was a wicked witch'),('Who ate everybody up');
      		 
       
      		 
      flush index_statistics;
      		 
      select * from ft where MATCH(c) AGAINST('wicked');
      		 
      show index_statistics;
      		 
      explain select * from ft where MATCH(c) AGAINST('wicked');
      		 
       
      		 
      # Cleanup
      		 
      set global userstat= @userstat.save;
      		 
      drop table ft;
