Using A Search Engine
Search engines are very powerful tools for searching the Internet for
information using keywords and phrases. Electronic scouts, known as
"robots" or "spiders" explore Web sites and
"index" each word within their pages. This information is then
compiled into a searchable database. When you enter a query into a
search engine, it matches your query words against the records it has in its
database to present a listing of possible documents meeting your request.
The key advantage to using a search engine to find your surnames is the size
of their index, which typically have information on millions and millions of
Web pages. This size does have its drawbacks, however. Due to
the sheer number of results possible with a search engine, there is often no
way (outside of visiting each one yourself) to determine the quality of the
links or their relevancy to your search topic. This can often leave
you more frustrated than when you began.
Search Engine Math
One of the best ways to focus your search is to use what many call Search
Engine Math. Two simple operators, add (+), subtract (-),
can go a long way toward narrowing your search results. These
operators are supported by the majority of the major search engines and
directories and are a lot easier to learn and remember for most users than
the Boolean operators AND, OR, and NOT.
Using the + Symbol
Beginning each keyword with a plus (+) symbol helps you to tell the
search engine to find pages that include all of the words that you
enter, not just some of them. For example, consider a search where
you are looking for the surname SMITH. Typing that name into
AltaVista brings up 3,002,420 pages which match your search request!
But assume that what you are really looking for is information on a man
named Jebediah Smith. You would want to look for pages which
contain both names. Typing in your search request this way:
+smith +jebediah would bring the number of results down to a much more manageable 635 pages. Now the majority of these pages probably have nothing to do with genealogy, but we will get to that in a moment. Using the - Symbol
The minus (-) symbol allows you to search for pages that have one word
on them but not another word. This is especially useful in the case of
surnames which have a dual meaning. For example, imagine you want
information about the surname RICE, but don't want to be
overwhelmed by pages relating to cooking and food. You could search
this way:
rice -food -cook
When you enter the term rice into AltaVista, 983,420 pages
are found which match your request. If you exclude the words food
and cook, as in the above example, the number of returned
pages drops to 787,800. That is still a lot of pages, but it's
almost 200,000 less than it was when you started!
This minus (-) technique also comes in handy when you want to
exclude information about celebrities (sports heroes, movie stars,
etc) who share your surname from your results. Next Page > More
