Scope

     Slurp, the Web crawler, indexes about 110+ million sites. It provides a good collection of features in a single easy-to-use interface. Timely reindexing of sites provides
     more updated sites than other search engines. Additional features include subject directories, discussion groups, search for businesses, people and e-mail addresses
     and classifieds, stocks and shareware.

Interface

     The customizable forms-based single interface lets you modify a search term from a drop-down list and choose advanced search options. You can limit the search to
     specific domains (such as .com or .org), geographic locations, very specific choices of media types and technologies, time periods and specified page depth. HotBot
     offers a language limit for nine languages, a personal page limit, and a check box for word stemming providing word variants of  a search term. The latest addition of
     choices is a pornography filter.

Logic

     Truncation is available by using the asterisk * .
     It allows specifying phrase searching or you can use quotation marks around a phrase.
     A "must not" button eliminates a term.
     A "should" selection tells the search engine to place more emphasis on that term.
     Boolean searches are supported through the menu options or using AND, OR and NOT.
     Matches any usage of uppercase characters with search terms.
     Date searching gives options for documents older or newer than a specified date, or content posted within the last few days, months or years.
     Searching for specific technologies on pages that contain Java, JavaScript, VRML (3 D), Acrobat, Shockwave, ActiveX, MP3, audio, video or image files is possible. Also, you
     can search for file type by suffix such as GIF.
     You may search by .edu to get educational institutions or .uk to get United Kingdom or by actual domain name of a specific Web site (www.hotbot.com.)
     The location button allows searching continents or countries for Web servers in those locations. The default is anyplace.

Results

     Relevancy of results is based on several factors; word frequency, number of times words appear in the title, document keywords and document length. Duplicate sites are
     listed with only one title, but all URLs are given. You may request search results in URLs only, brief description including title and summary, full description including title,
     summary, relevancy ranking and URL in increments of 10, 25, 50, or 100. Descriptions are pulled from <META> tags or top headings. A list of the ten most-visited sites
     for your topic is shown. These top ten hits from Direct Hit are incorporated into the regular search results if the output is set to ten and there are results available from
     Direct Hit.
