Bug #71551 ft_boolean_syntax has no impact on InnoDB FTS

Description:
The parameter ft_boolean_syntax has no impact on a boolean FTS search in InnoDB table:

How to repeat:
Change the "-" value by "$":
ft_boolean_syntax=+ $><()~*:""&|

and query in boolean mode:
SELECT * FROM deliverables WHERE MATCH (Description) AGAINST ('+new* $york' IN BOOLEAN MODE)

the "$" sign does not have the functionality of the old "-" sign (ignore word).

Server was restarted after the change, FTS index was rebuild on the table

Suggested fix:
Implement a new parameter:

innodb_ft_boolean_syntax=+ $><()~*:""&|

inline with innodb_ft_min_token_size, innodb_ft_enable_stopword.

Thank you for the report.

I cannot repeat described behavior and always get same result with '-' and '$'. Please provide repeatable test case: SHOW CREATE TABLE deliverables; few rows and sample output of queries SELECT * FROM deliverables WHERE MATCH (Description) AGAINST ('+new $york' IN BOOLEAN MODE); and SELECT * FROM deliverables WHERE MATCH (Description) AGAINST ('+new -york' IN BOOLEAN MODE);

If you use InnoDB please also try with current version 5.6.19: we fixed few Full Text bugs in InnoDB lately.

I am sorry: missed bug title. Please disregard previous comment. Verified as described.

Even more: InnoDB behave inconsistently with MyISAM.
