is incremented.
If -kw is specified, keywords and numbers of corresponding docu-
ments are output.
If -kt is specified, keywords and their related terms are out-
put.

estcmd version
Show the version information.
All sub commands return 0 if the operation is success, else return 1.
As for put, out, gather, purge, randput, wicked, and regression, they
finish with closing the database when they catch the signal 1 (SIGHUP),
2 (SIGINT), 3 (SIGQUIT), 13 (SIGPIPE), or 15 (SIGTERM).
The data type of attribute indexes specified by -attr option of create
sub command should be "seq" for sequential type, "str" for string type,
or "num" for number type.
Each pseudo index specified by -pidx option of search sub command and
so on is a directory containing files of document draft. If you search
a main index with pseudo indexes, meta search of the main index and
pseudo indexes is performed.
The encoding name specified by -ic option should be such name regis-
tered to IETF as UTF-8, ISO-8859-1, and so on. The language name spec-
ified by -il option should be one of "en" (English), "ja" (Japanese,
"zh" (Chinese), "ko" (Korean).
The outer command specified by -fx option of gather receives the path
of the target document by the first argument and the path for output by
the second argument. The original path of the target document is given
as the value of the environment variable `ESTORIGFILE'.
Note that similarity search is very slow, by default. To improve the
performance of similarity search, running "estcmd extkeys" beforehand
is strongly recommended.
