Like the manual says, "by doing this you *severely* decrease MySQL's ability to provide adequate relevance values for the MATCH() function. If you really need to search for such common words, it would be better to search using IN BOOLEAN MODE instead, which does not observe the 50% threshold." > 2) we have a custom stopword list This is run-time configurable. :-) Look at the ft_stopword_file variable. Every "word" in the file is used as a stopword. "Word" being defined the same as the indexing parser uses. > Is there any reason that these two settings, like FT_MIN_WORD_LENGTH, > cannot be moved to runtime-configurable params?

I just wish ft_min_word_len would be 3 by *default*, so we wouldn't have to change it. :-D Matt > > TIA > > -- > Shane Allen <[EMAIL PROTECTED]> > http://www.emphasys.net -- MySQL General Mailing List For list archives: http://lists.mysql.com/mysql To unsubscribe: http://lists.mysql.com/[EMAIL PROTECTED]
