I don’t think there is a formal document, but if you use the UI elements in the search results page (or the “options” link in the search widget, you can experiment with the various options and see the syntax appear once you have completed the form.

This is probably better handled as a separate support topic as it isn’t really related to the question posted by @Olivier_Lambert.
