When you start a search, the words you type in the search bar are called keywords. When choosing what keywords to type, you should select keywords that are specific to your research topic or question so you can find relevant search results quickly.
Avoid Full Sentences
It is assumed that every word you type into a search bar, whether in Google Scholar or a library database, needs to be in every search result. So, it is important that you avoid typing in full sentences like, "How does climate change impact sea turtles?".
In this example, I'd want to remove how and does and instead use the keywords climate change and sea turtles. By focusing on the main ideas of your research topic, you are making your search more specific and should be able to find more relevant search results
You can use AND, OR, and NOT to build a search phrase that helps narrow or broaden your search results.
You can also use " " quotation marks and ( ) parenthesis to build your search.
