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 registered to IETF as UTF-8,
ISO-8859-1, and so on. The language name specified 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.
