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.  The
     options are as follows:

     -a LEVEL | --anonymity=LEVEL
             This option can be used to specify additional anonymity constraints.  The default is
             1.  If set to 0, GNUnet will publish the file non-anonymously and in fact sign the
             advertisement for the file using your peer's private key.  This will allow other
             users to download the file as fast as possible, including using non-anonymous
             methods (discovery via DHT and CADET transfer).  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 discovery your identity.  You can gain better
             privacy by specifying a higher level of anonymity (using values above 1).  This
             tells FS that it must hide your own requests in equivalent-looking cover traffic.
             This should confound an adversaries traffic analysis, increasing the time and effort
             it would take to discover your identity.  However, it also can significantly reduce
             performance, as your requests will be delayed until sufficient cover traffic is
             available.  The specific numeric value (for anonymity levels above 1) is simple:
             Given an anonymity level L (above 1), each request FS makes on your behalf must be
             hidden in L-1 equivalent requests of cover traffic (traffic your peer routes for
             others) in the same time-period.  The time-period is twice the average delay by
             which GNUnet artificially delays traffic.  Note that regardless of the anonymity
             level you choose, peers that cache content in the network always use anonymity level
             1.

     -c FILENAME | --config=FILENAME
             Use the configuration file FILENAME (default: ~/.config/gnunet.conf)

     -h | --help
             Print the help page.

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

     -l FILENAME | --logfile=FILENAME
             Write logs to FILENAME.

     -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
     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.

FILES

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

EXAMPLES

           $ gnunet-search Das Kapital

     Searches for content matching the keyword "Das Kapital".

           $ 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.  The meta-data here is the
     description ("The GNU General Public License") and the mime-type  ("text-plain").   See  the
     options for gnunet-publish(1) on how to supply meta-data by hand.

     The full documentation for gnunet is maintained as a Texinfo manual.  If the info(1) and
     gnunet programs are properly installed at your site, the command

           info gnunet

     should give you access to the complete handbook,

           info gnunet-c-tutorial

     will give you access to a tutorial for developers.

     Depending on your installation, this information is also available in gnunet(7) and
     gnunet-c-tutorial(7).
