- 2. Four Search Strategies • Keyword Searching • Boolean • Question • Advanced
- 3. Keyword Searching • Enter terms to search • Use quotation marks to search as a phrase and keep the words linked together • Common words are ignored (that, to, which, a, the, …) • + and – can be used to include or exclude a word
- 4. Boolean Searching - AND • Enter words connect with AND - it will include sites where both words are found • Uses: joining different topics (ie. “global warming” AND California president Washington
- 5. Boolean Searching - OR • Enter words connect with OR - requires at least one of the terms is found • Uses: join similar or synonymous topics (ie. “global warming” OR “greenhouse effect”) dogs cats
- 6. Boolean Searching - NOT • Enter words connect with NOT – searches for the first term and excludes sites that have the second term • Uses: join similar or synonymous topics (ie. Washington NOT school) Washington school
- 7. Boolean – (Nesting) and Near • In a string of searching, terms placed in parentheses are searched first • Parentheses must be used to group items if there is another Boolean operator being used • NEAR may be used to require words to be found within 16 words of each other in the pages returned
- 8. Question Searching • A question may be entered in the search field of a search engine. • Ask Jeeves is a search engine that encourages the use of question searching
- 9. Advanced Searching • Advanced search features are offered on many engines by going to an “Advanced Search” page and making selections • This is effective in narrowing search returns to a specific topic or phrase Google Advanced Search
