Google has unveiled new web search customisation capabilities, which allow users to re-rank, delete, add and comment on search results.
SearchWiki allows signed-in users to click coloured icons beside search results to move preferred results to the top of the page, hide results from future searches or add a result not listed that they believe is relevant, Google explained.
Users will also be able to open a text box and type in a comment on a particular result, which will be made available to the user community.
All changes will remain when the same searches are carried out by a signed-in user, said Google in a blog posting.
"We've always said that the best search engine is the one that understands what the individual user wants," said Juergen Galler, Google's director of product management.
"SearchWiki really puts that in action: this is an even deeper level of customisation than we've offered before, because people know best what search results they're looking for."
