  2. Planning your searches • Plan your searches • Be specific and use multiple keywords • If you are searching for German shepherds in West Virginia, you will get better results using the terms German shepherd and West Virginia than if you just searched using the term dogs. • Try searching for different terms and synonyms. If car doesn’t work, try searching for automobile. Day 2: Tips on Search Wisely

  3. Fine-tuning your terms • Use phrases and quotation marks • “Springfield, Illinois” will return pages that reference only Springfield, Illinois with the words in that specific order. • Negative terms • Virus –computer will find pages that mention the word virus but not the word computer. • AND and OR queries • Most search engines automatically insert the word AND between phrases (which is why quotation marks are useful) so there is no need to type it in the search engine. OR is useful for searching for more than one term, such as West Virginia University OR WVU. Day 2: Tips on Search Wisely

  4. Keeping your search useful • Google ignores common terms such as where and how, as well as single digits and letters. • It is not case sensitive. Typing aNoThEr pHrAse will return the same results as another phrase. • To search for Roman numerals or a common word, either use quotations or the + sign. “Star Wars I” and Star Wars +I will return about the same results. • Use the site command • football site:wvu.edu will return pages that reference football, but only on WVU servers.

Sites like www.cnn.com will have more accurate information than sites like www.theonion.com. • How current is the information? Sites that have not been updated since 1998 are less likely to have accurate information. • Search engines are unfiltered and thus return all results that may not include results that are objective or even accurate. Think about the possible biases that could be portrayed and whether the information and data is authentic. • You can double-check your information against multiple sources if you are unsure of their authenticity or accuracy.
