Possibilities
. Try medical terms using the site:edu syntax.
. Try academic terms with the same syntax.
. Try any topical keyword combined with the intitle syntax.
. Use quotes to group your words into phrases as much as possible.
. Is there any word that will help your search if you make sure that it
doesn't appear in your queries? Try that by putting a minus in front
of the word ( -birds ).
are all search engine indexes created alike?
You  might  think  that  if  you  set  up  traps  on  one  search  engine  you  don't  need  to  bother  with 
them  on  others.  “They  all  index  the  internet,”  you  might  say.  “isn't  one  just  like  the  other?” 
deinitely not! only so much overlap exists in the indexes of the various search engines. if you 
only monitor one, you're deinitely going to miss information from the others. This might lead 
you to another question: “if i monitor all the major search engines, i'll be monitoring all the new 
pages  added  to  the  internet,  right?”  afraid  not.  Though  you'll  be  covering  a  lot  more  of  the 
internet than you would otherwise, all the search engines put together do not index more than 
a part of the internet's Web pages. 
Bottom  Line:  monitor  several  search  engines  and  you'll  get  all  you  can,  but  you  still  won't  be 
getting everything. 
Yahoo

Yahoo and Google. Because of that, Yahoo (yahoo.com) is being very proac-
tive in developing new syntax, updating its index of Web sites, and making
its Web search easier and easier to use. Yahoo started as a search engine
directory, and while the directory still exists, Yahoo is much more of a full-
text search engine now.
Building your queries
Like Google, Yahoo has a variety of syntax available and a large query limit.
Maximize both as much as you can. Yahoo's also got a couple of interesting
