问题
Im having an issue when my search includes the word "the" in my full text search.
Here is my search code with the problem:
SELECT * FROM names WHERE MATCH(myname) AGAINST ('+the' IN BOOLEAN MODE)
This one works fine:
SELECT * FROM names WHERE MATCH(myname) AGAINST ('+and' IN BOOLEAN MODE)
I already turned off the stop words in my CNF file, changed the min letters to 3 using both ft_min_word_len=3 AND innodb_ft_min_token_size=3
I'm using innodb. And returns 27000 results and 'the' returns 17000 from a db of about 500,000 records so im not hitting the 50% mark, even so, I'm using boolean mode. I can't find another word that breaks this. Any ideas?

Ok, I finally figured this out. It looks like I already had the myisam stopwords cleared but not the innodb ones. It's a little but harder to do than for myisam but here are the steps for anyone else that might need it:
In your /etc/my.cnf (or my.ini on windows) add these lines:
Create a stopwords table. I made mine in a db called settings and a table called innodb-stopwords. You cannot just set innodb_ft_enable_stopword = 0, you have to create and link to a table.
Make sure your table is innodb and add a column called value, varchar(?), utf8_general_ci. You can leave it empty or add values to the table.
innodb_ft_enable_stopword = 1
innodb_ft_server_stopword_table = settings/innodb-stopwords
Restart your mysql server.
Drop and recreate your fulltext indexes.
If you don't want to restart the server, you can dynamically set the variables with (also update the cnf/ini file for the next server restart)
--innodb_ft_enable_stopword=1
--innodb_ft_server_stopword_table=db_name/table_name
I don't see any workaround to recreating the index... you can do it in one command though so the table is locked the whole time and your users don't get errors:
ALTER TABLE `tablename` DROP INDEX indexname, ADD FULLTEXT(`columnname`);

Build a different stop-word list. Remove "the" and "and" from it.
