preview
An optional preview string or function that can be used to display results in the Ubiquity preview. For more info see Labs/Ubiquity/Ubiquity_0.5_Author_Tutorial#Adding_a_Preview
To provide a consistent search experience, makeSearchCommand can generate a preview for you with minimal work on your part. For more information on this, see #parser. If you leave out both preview and parser, the provided or generated description will be used instead.
charset
If you intended input and response cannot be represented properly by UTF-8, you can provide the required charset as a string. It must be a charset supported by nsIScriptableUnicodeConverter which should be all of the IANA Character sets
postData
Supplying postData will make Ubiquity use POST instead of GET when retrieving the results. It can be either a string ie: "q={QUERY}&hl=en" or as an object ie:
{"q": "{QUERY}", "hl": "en"}
