Scope
The newest of the major search engines features a unique ability to classify documents by topic and assign them to custom folders based on each individual search. A new relevancy ranking technology is based on link popularity and hypertext link information. It has one of the largest databases of the major search engines with 200 million items and growing.
It also has a set of "Special Collection" documents from about 5,500 sources including newswires, magazines and databases. Searching this group is free as is the bibliography and summary provided. There is a charge to view each full-text document. A free public access version of government Web sites in the usgovsearch database is also provided.

Interface

You may choose to search either the Web or Special Collection databases; the default is All Sources. It sorts the search results into Custom Search folders based on keywords, source etc. These results are divided into four folder types. Subject is assigned based on word occurrence and matches by keyword and makes browsing a large output much easier. Folders sorted by source are based on top level domain, host name, personal pages or the specific publication in the Special Collection database. The third folder, type of document, is less-commonly encountered. Even less often does the last folder type appear, by language. Within the folders may be subfolders. Field searching is available for URL, title, pub, text and others followed by a colon.
The other database, Special Collection, is full-text articles, many of which are not available elsewhere on the Web. Publication Search lets you search a specific publication in this group. Power Search options include searching for words in document title or URL, date range, specific countries, and even sort results by date. Source limits, language and document type limits can also be specified. Industry search allows 26 group choices.

Logic

  • In searching the default word is and between words.
  • Boolean terms or and not may be inserted between words or phrases in quotes.
  • Phrase searching requires quotation marks around each phrase.

 

  • Truncation is  automatic. You may use an asterisk (*) but plurals will be searched with entry of singular words.   A % sign can represent a single character either internally or at the end of a word after a minimum of four characters.
  • A + sign before a word or phrase in quotes indicates must include; a - sign is an eliminate-entirely situation.
  • Case sensitivity is limited to putting exact case match records ahead of other retrieved records in the results list.

Results

Ten hits are the default supplied at a time from a search. This engine gives the title of the document, percent ranking, type of Web site or document, summary, source date and URL. Results are clustered by site and publication. A list of the folders is provided on the left-hand side with Special Collection as the first one if you searched in that database.
