MYISAM_FTDUMP(1)	     MySQL Database System	      MYISAM_FTDUMP(1)

       myisam_ftdump - display full-text index information

       myisam_ftdump [options] tbl_name	index_num

       myisam_ftdump displays information about	FULLTEXT indexes in MyISAM
       tables. It reads	the MyISAM index file directly,	so it must be run on
       the server host where the table is located. Before using	myisam_ftdump,
       be sure to issue	a FLUSH	TABLES statement first if the server is

       myisam_ftdump scans and dumps the entire	index, which is	not
       particularly fast. On the other hand, the distribution of words changes
       infrequently, so	it need	not be run often.

       Invoke myisam_ftdump like this:

	   shell> myisam_ftdump	[options] tbl_name index_num

       The tbl_name argument should be the name	of a MyISAM table. You can
       also specify a table by naming its index	file (the file with the	.MYI
       suffix).	If you do not invoke myisam_ftdump in the directory where the
       table files are located,	the table or index file	name must be preceded
       by the path name	to the table's database	directory. Index numbers begin
       with 0.

       Example:	Suppose	that the test database contains	a table	named
       mytexttable that	has the	following definition:

	   CREATE TABLE	mytexttable
	     id	  INT NOT NULL,
	     txt  TEXT NOT NULL,
	     PRIMARY KEY (id),
	     FULLTEXT (txt)

       The index on id is index	0 and the FULLTEXT index on txt	is index 1. If
       your working directory is the test database directory, invoke
       myisam_ftdump as	follows:

	   shell> myisam_ftdump	mytexttable 1

       If the path name	to the test database directory is
       /usr/local/mysql/data/test, you can also	specify	the table name
       argument	using that path	name. This is useful if	you do not invoke
       myisam_ftdump in	the database directory:

	   shell> myisam_ftdump	/usr/local/mysql/data/test/mytexttable 1

       You can use myisam_ftdump to generate a list of index entries in	order
       of frequency of occurrence like this on Unix-like systems:

	   shell> myisam_ftdump	-c mytexttable 1 | sort	-r

       On Windows, use:

	   shell> myisam_ftdump	-c mytexttable 1 | sort	/R

       myisam_ftdump supports the following options:

       o   --help, -h -?

	   Display a help message and exit.

       o   --count, -c

	   Calculate per-word statistics (counts and global weights).

       o   --dump, -d

	   Dump	the index, including data offsets and word weights.

       o   --length, -l

	   Report the length distribution.

       o   --stats, -s

	   Report global index statistics. This	is the default operation if no
	   other operation is specified.

       o   --verbose, -v

	   Verbose mode. Print more output about what the program does.
