restrict your search?
Restricting the area in which a search engine will conduct the
search can help narrow down the number of results and possibly
give you better results.
Many search engines offer the ability to limit searches by
web page creation dates. This is a very useful tool for people
who will be doing continuing research on a specific topic - enabling
them to limit the results to pages created since their last search.
It is also useful when searching for current event topics.
NOTE: The implementation of this feature varies widely. Some search
engines like Yahoo offer radio buttons or pull-down menus, while
AltaVista and Hotbot provide the ability to specify dates or time
frames. Also, date restriction is related to the web page creation
date, not some historical time frame, i.e. it would not be useful
to use an engine's date capability to search for 1907 and information
relating to the Wright brothers, since there were no web pages
created in 1907 (in fact the web has really only existed in its
present form since 1991).
searches to specific parts of documents
Some engines can limit searches to specific areas of the webpage,
the most common being: title and URL.
Here's an example of a title search: If you are looking for information
on Alternative Medicine and believe that there are probably whole
websites or pages devoted to your subject which have the keywords
in the titles, you could use the syntax: title:
An example of URL search would be if you are looking for something
that you know will be in the Apple Computer website. You could
use: url: apple.com which
would return only web pages created by the computer maker Apple.
searches to specific areas of the web
Some engines allow you to limit your searches to "just the web"
or just "newsgroups."
searches to specific geographic locations
Some engines allow you to limit your searches to only webpages
hosted in specified country
searches to specific media
Both Hotbot and AltaVista
provide you with the ability to search for various types of media,
including audio, video, images, Java and VRML. If you are looking
only for images of Kathmandu using
image:Kathmandu in Alta Vista
will only find pages with images that have Kathmandu
in the name of the image.
Alta Vista also has an image search engine that will only look
for images AND it will display the results as thumbnails (small
pictures). Google also had a similar engine that displays thumbnails.
