NAME

       gnunet-search - a command line interface to search for content on GNUnet

SYNOPSIS

       gnunet-search [OPTIONS] [+]KEYWORD [[+]KEYWORD]*

       gnunet-search [OPTIONS] [+]URI

DESCRIPTION

       Search  for  content  on  GNUnet.  The keywords are case-sensitive.  gnunet-search can be used both for a
       search in the global namespace as well as for searching a private subspace.

       -a LEVEL, --anonymity=LEVEL

              The -a option can be used to specify additional anonymity constraints. If set to  0,  GNUnet  will
              try  to  download the file as fast as possible, including using non-anonymous methods.  If you set
              it to 1 (default), you use the standard anonymous routing algorithm  (which  does  not  explicitly
              leak  your identity).  However, a powerful adversary may still be able to perform traffic analysis
              (statistics) to over time infer data  about  your  identity.   You  can  gain  better  privacy  by
              specifying  a  higher  level  of  anonymity,  which increases the amount of cover traffic your own
              traffic will get, at the expense of performance.  Note that your download performance is not  only
              determined  by  your  own anonymity level, but also by the anonymity level of the peers publishing
              the file.  So even if you download with anonymity level 0, the peers publishing the data might  be
              sharing with a higher anonymity level, which in this case will determine performance.  Also, peers
              that cache content in the network always use anonymity level 1.

              This option can be used to limit requests further than that. In particular, you can require GNUnet
              to  receive certain amounts of traffic from other peers before sending your queries. This way, you
              can gain very high levels of anonymity - at the expense of  much  more  traffic  and  much  higher
              latency. So set it only if you really believe you need it.

              The  definition  of  ANONYMITY-RECEIVE  is  the  following.   0  means  no  anonymity is required.
              Otherwise a value of 'v' means that 1 out of v bytes of "anonymous" traffic can be from the  local
              user,  leaving  'v-1' bytes of cover traffic per byte on the wire.  Thus, if GNUnet routes n bytes
              of messages from foreign peers (using anonymous  routing),  it  may  originate  n/(v-1)  bytes  of
              queries  in  the  same  time-period. The time-period is twice the average delay that GNUnet defers
              forwarded queries.

              The default is 1 and this should be fine for most users.  Also notice  that  if  you  choose  very
              large  values,  you  may  end  up  having  no throughput at all, especially if many of your fellow
              GNUnet-peers all do the same.

       -c FILENAME, --config=FILENAME
              use config file (defaults: ~/.config/gnunet.conf)

       -h, --help
              print help page

       -L LOGLEVEL, --loglevel=LOGLEVEL
              Change the loglevel.  Possible values for LOGLEVEL are ERROR, WARNING, INFO and DEBUG.

       -o FILENAME, --output=FILENAME
              Writes a GNUnet directory containing all of the search results to FILENAME.

       -n, --no-network
              Only search locally, do not forward requests to other peers.

       -N VALUE, --results=VALUE
              automatically terminate the search after receiving VALUE results.

       -t DELAY, --timeout=DELAY
              Automatically timeout search after DELAY.  The value given must be a number followed  by  a  space
              and a time unit, for example "500 ms".  Note that the quotes are required on the shell.  Otherwise
              the search runs until gnunet-search is aborted with CTRL-C.

       -v, --version
              print the version number

       -V, --verbose
              print meta data from search results as well

NOTES

       You can run gnunet-search with an URI instead of a keyword.  The URI can have the format for a  namespace
       search    or    for    a    keyword    search.     For    a    namespace    search,    the    format   is
       gnunet://fs/sks/NAMESPACE/IDENTIFIER.  For a keyword search, use gnunet://fs/ksk/KEYWORD[+KEYWORD]*.   If
       the  format  does  not  correspond  to  a  GNUnet URI, GNUnet will automatically assume that keywords are
       supplied directly.

       If multiple keywords are passed, gnunet-search will look for content matching any of the  keywords.   The
       prefix "+" makes a keyword mandatory.

       # gnunet-search "Das Kapital"

       searches for content matching the keyword "Das Kapital".  Whereas

       # gnunet-search +Das +Kapital

       Searches for content matching both mandatory keywords "Das" and "Kapital".

       Search results are printed by gnunet-search like this:

            gnunet-download -o "COPYING" gnunet://fs/chk/HASH1.HASH2.SIZE

                 Description: The GNU General Public License

                 Mime-type: text/plain

       The  first  line contains the command to run to download the file.  The suggested filename in the example
       is COPYING.  The GNUnet URI consists of the key and query hash of the file and finally the  size  of  the
       file.  After the command to download the file GNUnet will print meta-data about the file as advertised in
       the search result, here "The GNU  General  Public  License"  and  the  mime-type  (see  the  options  for
       gnunet-publish on how to supply meta-data by hand).

FILES

       ~/.config/gnunet.conf
              GNUnet configuration file; specifies the default value for the timeout
