Keyword-rich searching

In his piece International Trade Article Visits published at http://internationaltrade.suite101.com/blog_print.cfm/international_trade_article_visits Daniel Workman writes: 'Studies show that people using search engines quickly look for answers to specific questions and will leave if not found within a couple of seconds.'
This comment highlights the need for people using search engines to think carefully about their keywords before they search, and especially to think about other possible synonyms or variants of their keywords. If they are searching for "export organisations" in a specific country they may need to also search for "organizations". This can be done effectively by using a Boolean search, or by using the Advanced search features which search engines provide.
The fact that Daniel Workman highlights the need for writers to use 'keyword-rich' articles should make us think about 'keyword-rich searching'.
