Updated Yahoo! Search Review

After realizing that the filetype: prefix did not work in Yahoo! any longer, I was digging around to find the proper prefix for the file types not included on their advanced search. Instead of filetype:, they are using the old Inktomi prefix of originurlextension:. So after verifying that it does work, not only for PDFs and other file types on the advanced search page, but also for .ps and .wpd and other extensions. So I also checked many of the other old Inktomi prefixes and found that more than I thought still worked (and more than when I checked last time). So I've updated the Yahoo! Search review to include stem:, domain:, feature:homepage, feature:index, feature:meta, and the region: limits. I'll be exploring these more in the future.

And yes, it has been a long time since my last post in April. I've made some small updates to the site during the interim. I plan on backfilling that time with some of the most significant (to me at least) of the search engine news from those misssing months.
