DESCRIPTION
       estcmd is an aggregation of sub commands.  The name of a sub command is
       specified by the first argument.  Other arguments are parsed according
       to each sub command.  The argument db specifies the path of an index.

       estcmd create [-tr] [-apn|-acc] [-xs|-xl|-xh|-xh2|-xh3] [-sv|-si|-sa]
       [-attr name type] db
              Create an index.
              If -tr is specified, a new index is created regardless if one
              exists.
              If -apn is specified, N-gram analysis is performed against
              European text also.
              If -acc is specified, character category analysis is performed
              instead of N-gram analysis.
              If -xs is specified, the index is tuned to register less than
              50000 documents.
              If -xl is specified, the index is tuned to register more than
              300000 documents.
              If -xh is specified, the index is tuned to register more than
              1000000 documents.
              If -xh2 is specified, the index is tuned to register more than
              5000000 documents.
              If -xh3 is specified, the index is tuned to register more than
              10000000 documents.
              If -sv is specified, scores are stored as void.
              If -si is specified, scores are stored as 32-bit integer.
              If -sa is specified, scores are stored as-is and marked not to
              be tuned when search.
              -attr specifies an attribute index and its data type.  This
              option can be specified multiple times.

              -kn specifies the number of keywords to be extracted.  By
              default, keyword extraction is not performed.
              If -um is specified, morphological analyzers are used for
              keyword extraction.

       estcmd purge [-cl] [-no] [-fc] [-pc enc] [-attr expr] db [prefix]
              Purge information of documents which do not exist on the file
              system.
              If prefix is specified, only documents whose URIs are begins
              with it.  It can be specified by the local path of a directory.
              If -cl is specified, regions of the deleted documents are
              cleaned up.
              If -no is specified, operations are printed but not executed
              actually.
              If -fc is specified, information of all target documents are
              deleted.
              -pc specifies the encoding of file paths.  By default, it is
              ISO-8859-1.
              -attr specifies an attribute search condition.  This option can
              be specified multiple times.

       estcmd extkeys [-no] [-fc] [-dfdb file] [-ncm] [-ni] [-kn num] [-um]
       [-attr expr] db [prefix]
              Create a database of keywords extracted from documents.
              If prefix is specified, only documents whose URIs are begins
              with it.
              If -no is specified, operations are printed but not executed
              actually.
              If -fc is specified, all target documents are processed
              whichever they have existing records or not.
              -dfdb specifies an outher database of document frequency.  By
              default, document frequency is calculated dynamically according
              to the index.
              If -ncm is specified, checking availability of the virtual
              memory is omitted.
              If -ni is specified, TF-IDF tuning is omitted.
              -kn specifies the number of keywords to be extracted.  By
              default, it is 32.
              If -um is specified, morphological analyzers are used for
              keyword extraction.
              -attr specifies an attribute search condition.  This option can
              be specified multiple times.

       estcmd words [-nl|-nb] [-dfdb file] [-kw|-kt] db
              Output a list of all unique words and each record size which is
              treated as docuemnt frequency.
              If -nl is specified, the index is opened without file locking.
              If -nb is specified, file locking is performed without blocking.
              -dfdb specifies an outer database where the result is stored.
              By default, the result is output to the standard output as TSV.
              If the outer database already exists, the value of each record
              is incremented.
              If -kw is specified, keywords and numbers of corresponding
              documents are output.
              If -kt is specified, keywords and their related terms are
              output.

       estcmd draft [-ft|-fh|-fm] [-ic enc] [-il lang] [-bc] [-lt num] [-kn
       num] [-um] [file]
              For test and debug.

       estcmd break [-ic enc] [-il lang] [-apn|-acc] [-wt] [file]
              For test and debug.

       estcmd iconv [-ic enc] [-il lang] [-oc enc] [file]
              For test and debug.

       estcmd regex [-inv] [-repl str] expr [file]
              For test and debug.

       estcmd scandir [-tf|-td] [-pa|-pu] [dir]
              For test and debug.

       estcmd multi [-db db] [-nl|-nb] [-ic enc] [-gs|-gf|-ga] [-cd] [-ni]
       [-sf|-sfr|-sfu|-sfi] [-hs] [-hu] [-attr expr] [-ord expr] [-max num]
       [-sk num] [-aux num] [-dis name] [phrase]
              For test and debug.

       estcmd randput [-ren|-rla|-reu|-ror|-rjp|-rch] [-cs num] db dnum
              For test and debug.

       estcmd wicked db dnum
              For test and debug.

       estcmd regression db
              For test and debug.

       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 sequencial 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.
