According to the docs - you can use this annotation to filter OSGi injections "OSGi injection can be filtered"

However - i am not finding use cases or examples with Sling Models that make use of this feature. 

Here is another code example of SLing Models (-but it does not use @Filter)

Thanks for your reply.

Went through the mentioned article, but still not able to get the use of below code available at

https://sling.apache.org/documentation/bundles/models.html 

@Inject@Filter("(paths=/bin/something)")private List<Servlet> servlets;

  By design, Servlets are not mean to be treated like services. Servlet technology is being used for communication between client & server over the HTTP protocol.

Yes, reason being calling servlet methods do not makes much sense.

       May be I am missing something here in case of servlet.

        Injecting any other service seems reasonable though.
