Some
explaination and hints:
There are three
search
options:
1. All : If you choose this one the search engine will find all
words
you type in the same page.
(Meaning a logical AND. Ex: "oil AND Nigeria")
2.Any: Now you will get pages with any of the words you searched
for.
(Meaning a logical OR. Ex: "oil OR Nigeria")
3.Boolean: Here you can tell the search engine to leave out pages
with
certain words.
(Meaning logical NOT. Ex. "oil NOT Nigeria").
So if you combine these three you can for example try a search like
this:
"oil AND (oilwatch OR Nigeria) NOT Norway"
You can also truncate a word by using the asterisk *. Searching for
"eco*"
will give you ecorates, economy, ecosophy etc. English common word
endings
will be added automatically.
