With fulltext search for MyISAM, I know that I can specify a stopword file in my.cnf with the following:
ft_stopword_file = '/etc/stopword.txt'
Can the same also be done with fulltext search for InnoDB? I'd like to do something like the following if possible:
ft_stopword_file_innodb = '/etc/stopword.txt'
However, I haven't seen any documentation indicating that stopwords for InnoDB can be stored in a file.
No, it cannot natively, hotwired, use a text file out of the box. That is, mysql as shipped. To achieve that you would need to write speciality UDF's which would be absurd considering the simple solution.
The information for custom Stop Words usage is available on this mysql manual page. It shows the rather limited default words out of the gates in the table INFORMATION_SCHEMA.INNODB_FT_DEFAULT_STOPWORD, how to reset to your own table, and the use of various system variables.
