							  *"Is it worth to run my own instance?"*
 | 
						
						
						
						
							 | 
							
							
 | 
						
						
						
						
							 | 
							
							\.\. is a common question among searx users.  Before answering this question,
 | 
						
						
						
						
							 | 
							
							see what options a searx user has.
 | 
						
						
						
						
							 | 
							
							
 | 
						
						
						
						
							 | 
							
							Public instances are open to everyone who has access to its URL.  Usually, these
 | 
						
						
						
						
							 | 
							
							are operated by unknown parties (from the users' point of view).  Private
 | 
						
						
						
						
							 | 
							
							instances can be used by a select group of people.  It is for example a searx of
 | 
						
						
						
						
							 | 
							
							group of friends or a company which can be accessed through VPN.  Also it can be
 | 
						
						
						
						
							 | 
							
							single user one which runs on the user's laptop.
 | 
						
						
						
						
							 | 
							
							
 | 
						
						
						
						
							 | 
							
							To gain more insight on how these instances work let's dive into how searx
 | 
						
						
						
						
							 | 
							
							protects its users.
 | 
						
						
						
						
							 | 
							
							
 | 
						
						
						
						
							 | 
							
							How does searx protect privacy?
 | 
						
						
						
						
							 | 
							
							===============================
 | 
						
						
						
						
							 | 
							
							
 | 
						
						
						
						
							 | 
							
							Searx protects the privacy of its users in multiple ways regardless of the type
 | 
						
						
						
						
							 | 
							
							of the instance (private, public).  Removal of private data from search requests
 | 
						
						
						
						
							 | 
							
							comes in three forms:
 | 
						
						
						
						
							 | 
							
							
 | 
						
						
						
						
							 | 
							
							 1. removal of private data from requests going to search services
 | 
						
						
						
						
							 | 
							
							 2. not forwarding anything from a third party services through search services
 | 
						
						
						
						
							 | 
							
							    (e.g. advertisement)
 | 
						
						
						
						
							 | 
							
							 3. removal of private data from requests going to the result pages
 | 
						
						
						
						
							 | 
							
							
 | 
						
						
						
						
							 | 
							
							Removing private data means not sending cookies to external search engines and
 | 
						
						
						
						
							 | 
							
							generating a random browser profile for every request.  Thus, it does not matter
 | 
						
						
						
						
							 | 
							
							if a public or private instance handles the request, because it is anonymized in
 | 
						
						
						
						
							 | 
							
							both cases.  IP addresses will be the IP of the instance.  But searx can be
 | 
						
						
						
						
							 | 
							
							configured to use proxy or Tor.  `Result proxy
 | 
						
						
						
						
							 | 
							
							<https://github.com/asciimoo/morty>`__ is supported, too.
 | 
						
						
						
						
							 | 
							
							
 | 
						
						
						
						
							 | 
							
							Searx does not serve ads or tracking content unlike most search services.  So
 | 
						
						
						
						
							 | 
							
							private data is not forwarded to third parties who might monetize it.  Besides
 | 
						
						
						
						
							 | 
							
							protecting users from search services, both referring page and search query are
 | 
						
						
						
						
							 | 
							
							hidden from visited result pages.
 | 
						
						
						
						
							 | 
							
							
 | 
						
						
						
						
							 | 
							
							
 | 
						
						
						
						
							 | 
							
							What are the consequences of using public instances?
 | 
						
						
						
						
							 | 
							
							----------------------------------------------------
 | 
						
						
						
						
							 | 
							
							
 | 
						
						
						
						
							 | 
							
							If someone uses a public instance, they have to trust the administrator of that
 | 
						
						
						
						
							 | 
							
							instance.  This means that the user of the public instance does not know whether
 | 
						
						
						
						
							 | 
							
							their requests are logged, aggregated and sent or sold to a third party.
 | 
						
						
						
						
							 | 
							
							
 | 
						
						
						
						
							 | 
							
							Also, public instances without proper protection are more vulnerable to abusing
 | 
						
						
						
						
							 | 
							
							the search service, In this case the external service in exchange returns
 | 
						
						
						
						
							 | 
							
							CAPTCHAs or bans the IP of the instance.  Thus, search requests return less
 | 
						
						
						
						
							 | 
							
							results.
 | 
						
						
						
						
							 | 
							
							
 | 
						
						
						
						
							 | 
							
							I see. What about private instances?
 | 
						
						
						
						
							 | 
							
							------------------------------------
 | 
						
						
						
						
							 | 
							
							
 | 
						
						
						
						
							 | 
							
							If users run their own instances, everything is in their control: the source
 | 
						
						
						
						
							 | 
							
							code, logging settings and private data.  Unknown instance administrators do not
 | 
						
						
						
						
							 | 
							
							have to be trusted.
 | 
						
						
						
						
							 | 
							
							
 | 
						
						
						
						
							 | 
							
							Furthermore, as the default settings of their instance is editable, there is no
 | 
						
						
						
						
							 | 
							
							need to use cookies to tailor searx to their needs.  So preferences will not be
 | 
						
						
						
						
							 | 
							
							reset to defaults when clearing browser cookies.  As settings are stored on
 | 
						
						
						
						
							 | 
							
							their computer, it will not be accessible to others as long as their computer is
 | 
						
						
						
						
							 | 
							
							not compromised.
 | 
						
						
						
						
							 | 
							
							
 | 
						
						
						
						
							 | 
							
							Conclusion
 | 
						
						
						
						
							 | 
							
							==========
 | 
						
						
						
						
							 | 
							
							
 | 
						
						
						
						
							 | 
							
							Always use an instance which is operated by people you trust.  The privacy
 | 
						
						
						
						
							 | 
							
							features of searx are available to users no matter what kind of instance they
 | 
						
						
						
						
							 | 
							
							use.
 | 
						
						
						
						
							 | 
							
							
 | 
						
						
						
						
							 | 
							
							If someone is on the go or just wants to try searx for the first time public
 | 
						
						
						
						
							 | 
							
							instances are the best choices.  Additionally, public instance are making a
 | 
						
						
						
						
							 | 
							
							world a better place, because those who cannot or do not want to run an
 | 
						
						
						
						
							 | 
							
							instance, have access to a privacy respecting search service.
