The magnifying glass icon could be replaced by the icon of the plugin that matches the selected result.
So if there's query results from multiple plugins, you can select any of them with the arrow buttons and the icon on the top right will tell you what plugin was responsible for that result.
This will make it immediately clear to users what plugin produced the result as we have had several cases where the user mistaken the result coming from a different plugin.
