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).
