Scope
Currently the largest search engine,
indexing some 1.25 billion web pages.
It is a full-text index that searches
the entire HTML file.
Interface
Google offers both simple and advance
search capabilities. Advanced searching
allows you to limit a search by including
or excluding desired words or phrases,
and allows for language-specific requests.
Google will also permit expanding
the list of results from 10 hits to
100 hits. A “Page-specific Search”
is also included in which both pages
that link to a page and pages that
are similar to a page can be requested.
Google also offers specialized searches
on such topics as Apple Macintosh,
BSD Unix, Linux, and U.S. Government.
It will also perform university searches.
Other services
Google will search in any language,
and allow limiting to 15 languages
including all major European languages
and English (and includes Japanese,
Korean and both simplified and traditional
Chinese). An additional 10 languages,
mostly eastern European, are also
available.
Logic
- In simple searching the default
word is and between words.
- Phrase searching done by enclosing
in quotation marks.
- Truncation is not available.
- No case-sensitive considerations.
Results
The hit display shows title, URL,
first two lines with search terms
highlighted in boldface, and size
in bites. Additional features are
a “cached” link where Google takes
a “snapshot” of a the page as it crawls
the web and a “similar pages” link
which prompts GoogleScout to search
the web for pages related to the resultant
search.
