mgpp_invf_dict(1)

NAME
mgpp_invf_dict - build an `on-disk' stemmed dictionary

SYNOPSIS
mgpp_invf_dict [ -h ] [ -b entries-per-block ]
[ -d directory ] -f name

DESCRIPTION
mgpp_invf_dict builds an `on-disk' stemmed dictionary from the compressed stemmed dictionary that can be used during querying. 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. The dictionary is blocked with each block containing the same number of entries (not the same size).

OPTIONS
Options may appear in any order.

-h  This displays a usage line on stderr.

-b entries-per-block
    The dictionary is stored in blocks on disk; this option is used to specify the number of entries per block. The default is 16.

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

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

ENVIRONMENT

MGDATA
    If this environment variable exists, then its value is used as the default directory where the mgpp 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.

FILES

*.invf
    Inverted file.

*.invf.dict
    Compressed stemmed dictionary.

*.invf.dict.blocked
    The `on-disk' stemmed dictionary.

*.invf.idx
    The index into the inverted file.
