Greg Notess (also a librarian) has posted a couple of new and interesting items on his Search Engine Showdown site.
You'll find a:
+ A look at how the major web engines handle long words. Notess writes, "The long word showdown found that Gigablast ranked best for long word searching since it could handle a query with a word 1,896 characters long. Google can't handle a 155 character query that both MSN and Yahoo! can find."
+ An item about how Yahoo is now searching stop words in phrases and how it "breaks" several "hacks" for Yahoo proximity searching. I agree with Greg, Yahoo needs to bring back both truncation and the proximity operator that were once available at AltaVista.
