You can choose what service to use using a service menu located in the preferences bar at the top of the Noflail Search page, and you can switch at any time from one service to another. The icon of the selected service is shown next to the service menu, and also next to every query in the Search History and every result in the Results panel.
To export a result, click on the service icon next to it. This causes the URL of the result to be exported to the selected service, together with the result title and description. You can thus bookmark the result in Delicious or Diigo, or upload the result to your Facebook profile. Notice that you can export a result before or after you follow its link.
To export a query, click on the service icon next to it. This causes a query URL to be exported to the selected service. When you later click on a bookmark or link that targets the URL, you are taken to Noflail Search and the query is run immediately. The query URL records the search terms, the search engine that was used to run the query, the site and language restrictions if any, and your country/language as specified in the orange top bar when the query was issued.
