Yahoo! no longer full Boolean

Greg Notess reports in Online that Yahoo! no longer has full support for Boolean searches.

As I point out in my book, Genealogy Online 8th Edition, you can do a lot of good research using search engines and Boolean operators (AND, NOT, OR, and parentheses.) One of the first search engines, Yahoo!, has stopped supporting the operators NOT and AND, although the plus or minus sign in front of a term still work.

The NOT is very important to genealogists searching for surnames that are also common words: BROWN, FOX, BANKS, & WEEKS are just some examples.  To find genealogy pages for these surnames in Yahoo, be sure now to put a minus-sign directly in front of a term that you want excluded from search result (meaning that Yahoo! will exclude pages that has that term in their text) and a plus sign in front of terms you must have. So to get hits for pages with genealogy and Banks surname, instead of

BANKS AND GENEALOGY NOT FINANCE NOT RIVER

you would formulate it as

+BANKS +GENEALOGY -FINANCE -RIVER

The OR operator still works, and the AND is assumed if you use no operators, but nesting with parentheses doesn’t as in

+(BANKS AND GENEALOGY) - (FINANCE OR RIVER)

Advanced Google still accepts the most popular Boolean terms, and Exalead even supports the NEAR operator, which really helps with common surnames. Still, as Notess says: “Live Search is now the only major search engine with full Boolean support.”

Wow. Microsoft leading in power-user technology and Yahoo! dumbing down. Who’d a thunk it?

This is short-sighted on Yahoo!’s part. While many users may not appreciate the power of the Boolean terms, users such as librarians, journalists and genealogy researchers love them. Rethink this, Yahoo! We need our Boolean boogie!
