In Google and Databases always search using Keywords not Questions
You’re trying to find great articles that have the answers to your questions - If you’re trying to find the answers, why would you search by typing in the questions?
Typing in full questions, long phrases or sentences may lead to few or NO results
Think (carefully) about the topic and questions you’re trying to explore and write down the keywords that will help you find the main ideas
Brainstorm and list as many keywords as possible (use synonyms too)
Check your spelling
Don't stop at one search (especially if it isn't very successful), the results are only as good as the keywords you use
Good Keyword searches usually contain 2 - 4 Keywords (the more keywords you use, the narrower your results)
Once you find information about your topic, pay attention to words that occur frequently and add them to your keyword list
