Htmerge is used to create a document index and word
database from the files that were created by
htdig. These databases are then used by
htsearch to perform
the actual searched.
In addition to the command line options, the environment
variable TMPDIR will be used to designate the
directory where intermediate files are stored during the
Use alternate work files. Tells htdig to append
.work to database files, causing a second copy of
the database to be built. This allows the original
files to be used by htsearch during the indexing run.

Merge the databases specified by merge_configfile
into the databases specified by -c or the default.
You will need a separate config file for each of
the two databases. Then each file will set the
attribute to change the name of the databases, so
they are in different directories or files.
Note: You must run htmerge
separately on each of the databases created by
htdig before merging them
together with this option. This is because merging
the two wordlists together requires wordlists that
have already been cleaned up by htmerge.
Because the -m option allows you to specify only
one database to be merged into the other, and only
one -m option may be specified, if you need to merge
three or more databases together you must run htmerge
multiple times with the -m option.
Print statistics about the document and word databases
after htmerge has finished.
Run in verbose mode. This will provide some hints as to
the progress of the merge. This can be useful when
running htmerge interactively since some parts
(especially the word database creation) can take a very

The LOCALE or LC_COLLATE environment variable
may also affect the sorting process, so it's wise to set
LC_COLLATE=C before running htmerge to avoid
having the wordlist sorted in an unexpected collating sequence.
