In last few days before I am telling you about the Google Search experimental tool called SearchWiki, saying that it would allow users signed into Google to change the ranking of personal search results. The tool also lets users delete or add comments to searches. Now Google SearchWiki found Bugs, so Google had pulled back the SearchWiki feature to fix a bug in the system and the search engine innovator would be working to improve this ‘experimental’ feature.
