mg_invf_dict - build an `on-disk' stemmed dictionary


mg_invf_dict [ -h ] [ -F ] [ -b num ] [ -d directory ] -f name


mg_invf_dict builds an `on-disk' stemmed dictionary from the compressed stemmed dictionary that the mgquery(1) program can access. Each entry in the dictionary contains the disk pointer to the associated inverted file entry, and various other pieces of information about the stemmed word.


Options may appear in any order.

This displays a usage line on stderr.

-b num
The dictionary is stored in blocks on disk; this option is used to set the block size. The default is 4-KB blocks.

This option causes the disk blocks to be aligned on the appropriate boundaries. For example, if 4-KB blocks are used, they will be aligned in the file on 4-KB boundaries.

-d directory
This specifies the directory where the document collection can be found.

-f name
This specifies the base name of the document collection.


MGDATA If this environment variable exists, then its value is used as the default directory where the mg(1) collection files are. If this variable does not exist, then the directory "." is used by default. The command line option -d directory overrides the directory in MGDATA.
