Re: finding other syntax, have you seen https://answerthepublic.com ?

That site lets you type in some key words and then it finds what questions people are searching for on Google based on those keywords (with prefixes like "who", "what", "where", and search suggestions).

Then it makes a nice big graph of the questions.

That's an amazing resource, thanks for sharing. Using autosuggestions might actually be really useful.
