This is a good idea, but in ft_boolean_syntax I see more chars which should not be true_word_char. So what I should do when I have such string : "--~><(+) And I want to find it by fulltext search. I know that looks strange :) But i've idea: Redefine true_word_char (misc_word_char is null) #define true_word_char(X) (isgraph(X)) and mysql parser should understands escaping char. So string "--~><(+) I can search by typing : \"\-\-\~\>\<\(\+\) Is any chance to implement escaping char feature ? Maybe there is another solution for my problem ? Best regards. P.S. I posted this mail to [EMAIL PROTECTED] but nobody replaed, mabye here I'll have more luck. -- Grzegorz mysql,sql --------------------------------------------------------------------- Before posting, please check: http://www.mysql.com/manual.php (the manual) http://lists.mysql.com/ (the list archive) To request this thread, e-mail <[EMAIL PROTECTED]> To unsubscribe, e-mail <[EMAIL PROTECTED]> Trouble unsubscribing?
