				|  |  | +==================================
 | 
	
		
			
				|  |  | +Limit access to your searx engines
 | 
	
		
			
				|  |  | +==================================
 | 
	
		
			
				|  |  | +
 | 
	
		
			
				|  |  | +Administrators might find themselves wanting to limit access to some of the
 | 
	
		
			
				|  |  | +enabled engines on their instances. It might be because they do not want to
 | 
	
		
			
				|  |  | +expose some private information through an offline engine. Or they
 | 
	
		
			
				|  |  | +would rather share engines only with their trusted friends or colleagues.
 | 
	
		
			
				|  |  | +
 | 
	
		
			
				|  |  | +Private engines
 | 
	
		
			
				|  |  | +===============
 | 
	
		
			
				|  |  | +
 | 
	
		
			
				|  |  | +To solve this issue private engines were introduced in :pull:`1823`.
 | 
	
		
			
				|  |  | +A new option was added to engines named `tokens`. It expects a list
 | 
	
		
			
				|  |  | +of strings. If the user making a request presents one of the tokens
 | 
	
		
			
				|  |  | +of an engine, he/she is able to access information about the engine
 | 
	
		
			
				|  |  | +and make search requests.
 | 
	
		
			
				|  |  | +
 | 
	
		
			
				|  |  | +Example configuration to restrict access to the Arch Linux Wiki engine:
 | 
	
		
			
				|  |  | +
 | 
	
		
			
				|  |  | +.. code:: yaml
 | 
	
		
			
				|  |  | +
 | 
	
		
			
				|  |  | +  - name : arch linux wiki
 | 
	
		
			
				|  |  | +    engine : archlinux
 | 
	
		
			
				|  |  | +    shortcut : al
 | 
	
		
			
				|  |  | +    tokens : [ 'my-secret-token' ]
 | 
	
		
			
				|  |  | +
 | 
	
		
			
				|  |  | +
 | 
	
		
			
				|  |  | +Unless a user has configured the right token, the engine is going
 | 
	
		
			
				|  |  | +to be hidden from him/her. It is not going to be included in the 
 | 
	
		
			
				|  |  | +list of engines on the Preferences page and in the output of
 | 
	
		
			
				|  |  | +`/config` REST API call.
 | 
	
		
			
				|  |  | +
 | 
	
		
			
				|  |  | +Tokens can be added to one's configuration on the Preferences page
 | 
	
		
			
				|  |  | +under "Engine tokens". The input expects a comma separated list of
 | 
	
		
			
				|  |  | +strings.
 | 
	
		
			
				|  |  | +
 | 
	
		
			
				|  |  | +The distribution of the tokens from the administrator to the users
 | 
	
		
			
				|  |  | +is not carved in stone. As providing access to such engines
 | 
	
		
			
				|  |  | +implies that the admin knows and trusts the user, we do not see
 | 
	
		
			
				|  |  | +necessary to come up with a strict process. Instead,
 | 
	
		
			
				|  |  | +we would like to add guidelines to the documentation of the feature.
 | 
	
		
			
				|  |  | + 
 | 
	
		
			
				|  |  | +Next steps
 | 
	
		
			
				|  |  | +==========
 | 
	
		
			
				|  |  | +
 | 
	
		
			
				|  |  | +Now that searx has support for both offline engines and private engines,
 | 
	
		
			
				|  |  | +it is possible to add concrete engines which benefit from these features.
 | 
	
		
			
				|  |  | +For example engines which search on the local host running the instance.
 | 
	
		
			
				|  |  | +Be it searching your file system or querying a private database. Be creative
 | 
	
		
			
				|  |  | +and come up with new solutions which fit your use case.
