Since we have three documents in our file server, we can add them to Goophr using the following curl commands:

$ curl -LX POST -d '{"url":"http://file_server:9876/book1","title":"Book 1"}' localhost:9090/api/feeder | jq  && 
> curl -LX POST -d '{"url":"http://file_server:9876/book2","title":"Book 2"}' localhost:9090/api/feeder | jq  && 
> curl -LX POST -d '{"url":"http://file_server:9876/book3","title":"Book 3"}' localhost:9090/api/feeder | jq
