We’ve removed all search tables that relied on the BOSS v1 API (search.web, search.image, and search.news) as the aforementioned BOSS v1 no longer exists as of today (http://www.ysearchblog.com/2011/06/30/you-asked-for-this-boss-v2-updates/).
For those of you relying on those tables please consider using the community BOSS v2 table (https://github.com/yql/yql-tables/blob/master/boss/boss.search.xml).
Thanks -YQL Team
