Search Engine

I have used google as the search sengine to retrieve information on my topic. The phrase I have used was "(Discuss*) AND (Drug* OR Medicine*) AND (Abuse* OR Mistreatment* OR violence *) AND (Youth* OR Adolescence *)"

Subject directory

I have used Yahoo subject directory to search for information by using the same phrase as the keyword.

I have metacrawler as a meta search engine by using the phrase as the keyword.
