bare bones lesson 14: GIGABLAST

 

 


GIGABLAST :   A Closer Look


DESCRIPTION:

GigaBlast is a newer search engine, originating in 2002.  Its database is small, especially  when compared to Google, MSN, and Ask, but it has some very nice features.  One is "Giga-Bits," which displays "related concept listings" at the top of the results page. Also at the top of the results page are additional links to reference pages (for research purposes) and related pages that help you narrow and customize your subject search. On its basic page, GigaBlast offers separate search links for the Web and its subject directory. It also links to blog, travel, and gov. searches, but these are currently in BETA (test) phase. In its index, GigaBlast includes PDF, Microsoft Word, Powerpoint, PostScript, and Excel files.  It has a nice date-reporting feature that links to both the date indexed and the date last modified. (See the URL line)   Its Advanced page, while lacking several advanced search features, is clean, simple, and easy to use.

OR, at the end of results list

SEARCH OPTIONS:

Basic Search Page

  • Supports (+) and (-) signs
  • Supports double quotes (" ")

Advanced Search Page

  • Supports Boolean-type searches for "all of these words," "this exact phrase," "any of these words," and "none of these words"
  • Allows for two phrase searches at the same time with two "this exact phrase" boxes

OTHER SEARCH OPTIONS AND FEATURES:

  • Features "Giga-Bits," i.e., related concept listings, Reference Pages, and Related Pages in shaded areas preceding search results
  • Provides links to other search engines (Google, Yahoo, DMOZ, Ask, & MSN) at bottom of search page, with invitation to try your search there as well
  • Maintains stop word list; will not search for stop words unless typed as part of a phrase within quotation marks or if preceded by a (+) plus sign
  • Offers short answers to simple sentence queries, but this feature doesn't work very well and can be a waste of time.

ASSIGNMENT:

To see how the "Giga-Bits" feature works, go to the Basic search page, and search for:
