It seems my wishes has come true and Google has finally launched a Blogsearch service.
It does not have all the bells and whistles of other blog search tools, you cannot restrict searches to OPML feeds etc, but I’ve never used those features in the competition. I just do a simple text search and want results.
The search supports all the usual google search modifiers like link: but also has some blog specific stuff: inblogtitle:, inposttitle:, inpostauthor:, blogurl:, more at the FAQ.
UPDATE: Scoble is doing some comparisons between google and others, check his blog for new entries but so far see these: 1, 2, 3.
NOTE: This is a static archive of an old blog, no interactions like search or categories are current.
