Ummm, the BOW (and the entire three database structure) no longer exists AFAIK. Ink made some major changes late last summer. From this article [news.com.com]:
Inktomi, for example, recently increased the frequency and depth of its search engine to "crawl" about 2 billion documents on the Web every two weeks--a benchmark that rivals Google and Fast. Just a week ago, it searched only about 500 million documents about every month, according to Vish Makhijani, vice president of Web search at Inktomi. Fast in the last week announced that it is searching 2.4 billion documents.
In addition, they rolled out Web Search 9 [inktomi.com] last fall.
