@item @code{ft_min_word_len}

The minimum length of the word to be included in a @code{FULLTEXT} index.

@strong{Note: @code{FULLTEXT} index have to be rebuilt after changing

this variable.}

@code{OPTIMIZE TABLE}) after changing this variable.}

@item @code{ft_max_word_len}

The maximum length of the word to be included in a @code{FULLTEXT} index.

@item @code{ft_max_word_len_sort}

The maximum length of the word in a @code{FULLTEXT} index

to be used in fast index recreation method in

@code{REPAIR}, @code{CREATE INDEX},  or

@code{REPAIR}, @code{CREATE INDEX}, @code{OPTIMIZE TABLE}, or

@code{ALTER TABLE}.  Longer words are inserted the slow way.

The rule of the thumb is as follows: with @code{ft_max_word_len_sort}

increasing, @strong{MySQL} will create bigger temporary files

When @code{ft_max_word_len_sort} is too small, instead,

@strong{MySQL} will insert a lot of words into index the slow way -

but short words will be inserted very fast. It applies only to

Index recreation during @code{REPAIR}, @code{CREATE INDEX}, or

@code{ALTER TABLE}.

@item @code{have_bdb}

@code{YES} if @code{mysqld} supports Berkeley DB tables. @code{DISABLED}

Minimal length of word to be indexed is defined by @strong{MySQL}

variable @code{ft_min_word_length}. @xref{SHOW VARIABLES}.

Change it to the value you prefer, and rebuild

your @code{FULLTEXT} indexes.
