Google today announced that it has brought its "Search Options" results filtering feature to certain mobile platforms, including the iPhone OS, for U.S. users. The feature allows users to filter their search results by timeframe and by source, such as the entire Web or just Internet forums or reviews.
Today in the US, we are making Search Options available on Android/iPhone/Palm WebOS devices so that you can slice and dice your mobile search results as well. For example, suppose you are shopping at a store for a camera, and you would like to see what users have been saying about a specific model within the past week. You can do this simply by searching for the name of the product. Then, on the search results page, use "Options" to filter by "Forums" and refine further by choosing "Past week".
The feature was introduced to standard search results in May, but has now been extended to mobile-formatted results on certain platforms to provide enhanced search capabilities.
