You can use the following search techniques :
Search Levels:
- Basic Search: Use a simple strategy when the question is related to one term and is not linked to other terms. Example: Psychology.
- Advanced Search: Use the compound strategy when your research includes two topics or more than one aspect. Example: Contribution of psychology to education.
Search by Material Type:
- You can use the tabs in the Google search engine to get better results.
- Example: Pyramids Image at Night. Search for "Pyramids", Select "Image" tab and choose "Black" color.
Boolean Search
Use Boolean operators to specify searches such as:
- AND: To narrow the search results with pages that contain all of the search terms. Example: children AND school AND bullying
- OR: To expand the search results with pages that contain any of the search terms. Example: United Nations OR UN, "global warming" OR "climate change", color OR colour
- NOT: To exclude results that contain the second search term.
Phrase Search
- Use quotations marks (" ") to search terms as a phrase and narrow your results. Retrieved results will contain exact words in the exact order typed.
- Example: names, concepts, book title, or article titles such as “Spillover of COVID-19: impact on the Global Economy” or “climate change”.
Truncation Search
- Use the asterisk symbol (*) to search for various endings to root words.
- Example: comput* to find the words 'computer' or 'computing'.
Wildcard Characters Search
- Use the question mark symbol (?) to replace any single character of the word.
- Example: wom?n: results will contain 'woman' or 'women'
Plus (+) and Minus (-) Symbols
- Use the plus (+) symbol to include all terms in the search results. Example: COVID+Qatar, Organic+Food.
- Use the minus (-) symbol to exclude the second term in the search results. Example: programming-python.
Two Consecutive Colons
- Use consecutive dots (..) to show search for results within a specific time period by placing a (..) between two numbers.
- Example: US Presidents 1700..2000, Medical Patents 2010..2020, Windows 2010..2020.
