 You can use phrase searching to make sure the words you're searching for are found together. To understand how this works, let's use the following research question as a basis. When you enter search terms into a search box, most databases treat the words separately. Your search results will include articles and books, etc., in which the words appear somewhere, not necessarily together. You end up with a large number of search results, many of which may be irrelevant to your search. To improve the relevance of your results, you may want the database to retrieve results that only contain certain groups of words together. These are called phrases. For example, electric cars and environmental impacts are both phrases. To ensure groups of words are found together, just place quotation marks around the words. This causes the database to search for articles containing those exact phrases, so you end up with fewer results, but they're more relevant to your search.
