Soovle is a very cool service that allows you to quickly collect and download search tips from Google, Bing, Amazon, Answers.com, Yahoo, Wikipedia and Youtube. It is inconvenient that there is no way to collect hints for the whole word and for parts of the word at the same time. There is also no way to collect hints for a large number of keywords at once. This means you have to type one word at a time. In any case, it is worth a try and is a great way to find ideas for extending the semantic.
