The Modify Search Engines window controls TV Rename’s outgoing interface with the world (other than TheTVDB). Here, you can configure how and where TV Rename points a web browser searching for files.
Using the Add and Delete buttons you can create or remove records at will, and the Tags... pop up a list of supported tags to remind you whats available. (The tags supported are the same as those listed in the Filename Template Editor.)
As an example, here is a URL entry for Google.
https://www.google.co.uk/search?q={ShowName}+S{Season:2}E{Episode}
The list of URL’s can be used when the When to watch tab is open, the last used entry becomes the default, and appears in a text box to the right of the Refresh button. It can be changed by clicking the ▼ button and selecting another entry.
With a little ingenuity you can get really creative with these entries and pass your search to its specific target through a web proxy.
