The rule of thumb... use POST when you want to send or "post" data to a server, like submitting an application form. POST can handle sending a lot more data.
Use GET when you want to retrieve or "get" data from a server, like search results or database record data. Only send the key data needed to retrieve what you want, like a unique ID. Then that data will be in the URL if the user want to bookmark the page.
