According to a blog post, Google has launched a search feature that lets signed-in users delete, add or re-rank comments on search results. The feature is called SearchWiki and it represents an example of how search is becoming increasingly dynamic. Google says that, by giving people tools, search will become more useful. Anthony House, spokesman at Google, says that people who do the same search frequently can remove a site from the results, if it’s not of interest for them. Furthermore, users can add comments to a site, which will pop up every time that site is in the results. If a user searches for a sports site, he can add a comment to the site in order to remember that it has a lot of interesting information, for example.

Of course, re-ranked search results or other things like this will not affect other people’s results. However, there is also an option that allows a user to see how other people customized their search, which can be accessed by clicking “see all notes for this SearchWiki” at the bottom of the page. Users can further personalize search results by typing in the URL of a site they want to add to the results of a given search or move a site to the top of the search results.

Users can keep track of all the changes they have made to a search by clicking on “see all my SearchWiki notes”. They can also remove edits or comments and go back to the usual search results. In order to use SearchWiki, you must be signed in and English must be the preferred language. Juergen Galler, Google’s director of product management, told the media: "SearchWiki really puts that in action: this is an even deeper level of customization than we've offered before, because people know best what search results they're looking for."
