NAME
mg_invf_dict - build an `on-disk' stemmed dictionary
SYNOPSIS
mg_invf_dict [ -h ] [ -F ] [ -b num ] [ -d directory ] -f name
DESCRIPTION
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
Options may appear in any order.
- -h
- 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.
- -F
- 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.
ENVIRONMENT
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.- *.invf
- Inverted file.
- *.invf.dict.build
- Compressed stemmed dictionary.
- *.invf.dict
- The `on-disk' stemmed dictionary.
- *.invf.idx
- The index into the inverted file.
