Search engines like it best when you use keywords or phrases, rather than sentences when searching. Break down your topic or question into a few keywords.
For example, if your topic was:
"Discuss the prevalence of cheating in exams at University"
Your keywords would be:
Search engines only search the exact words you input.
It's important to search a variety of search words, as not every author will use the exact same words that you have chosen to search.
For example: searching "education" as well as "schooling" will broaden your search, and help you pick up more search results.
If it's necessary to provide a list of references or a bibliography as part of your project submission, it's best to keep track of the sources you have read and/or cited as you go along. Doing this will save you the headache of scrambling at the last minute to find the full information needed to correctly cite the source in your reference list.
You can combine multiple keywords or concepts together in your search, using search operators, known as "Boolean connectors" or "Boolean operators". They are: AND, OR, and NOT.
Using connectors can improve the relevancy of your results, as the search engine or database will search your keywords in a more specific and filtered way.
In many databases, (and Google) if you don't use a connector between your search words the AND connector automatically applies to your search.
For example, the keyword search: Brexit voting Wales would be interpreted as Brexit AND voting AND Wales.
Using OR between your search words will connect two or more similar concepts together; the database will find at least one of your terms present in the results, thus broadening your search results
