The settings page of the Online Search Plugin
In the Name field, you can change the name of this plugin. This name is then subsequently used for the plugin in the program menu and the layout-manager. If you have several Online Search Plugins running in your layout, you should assign a different name to each of them.
The next two dropdown boxes let you choose your preferred Language for a search site and the search Site itself. Below these two dropdown boxes, the Host Lookup text indicates, whether your chosen language is (probably) supported or not supported by your chosen search site. As a fallback, the Site always operates in its default language.
In the Headline field, you can change the headline of this plugin. This name is then subsequently displayed as the title of the search window in your desktop. If you have several Online Search Plugins running in your layout, you should assign a different name to each of them. It is good practice to choose a Headline that is close to the name of the search Site you want to use.
