Intro

• Theoretically, the AlltheWeb database is now essentially the same database is the as the Yahoo Search database because Yahoo acquired AlltheWeb as well as other search engines. hich produces database seaching products and provides online marketing services. Yahoo is now using that search engine database (replacing its licensed Google subset) and incorporating it in or licensing it out to other search engines. The database has some new capabilities lacking in the databases that it replaces, but it also has cause the elimination of some tools proprietary to the former databases (such as AltaVista Advanced's "near" proximity operator and truncation).
• Size: Well, according to Ujiko, probably about four-billion Web pages and other files, but it is unclear how large and what part of the Inktomi/Overture database is used in each of the search engines.

Search functionality

• Advanced Search enables Boolean searching through the use of entry fields or in a Boolean entry field. The latter supports nesting.
