Which of the following searches will be more effective?
A) Are school vouchers good or bad for public schools?
B) "school vouchers" AND "public schools" AND issues
The answer is typically B - keywords and phrases.
In most cases, you do not want to type in a long sentence or sentence fragment. Taking your search topic and translating it into the most important keywords that describe your topic is the most effective search technique. The cases in which you would want to use a sentence as your search phrase is when you are gathering background information, you are having trouble effectively searching with keywords, or it is likely authors will use such similarly worded sentences in their articles.
Other tips regarding keywords:
To search for two or more words in an exact order, place quotation marks around the phrase. The computer will only return documents containing that specific phrase rather than documents containing each word found individually anywhere in the document.
EX: "obsessive compulsive disorder"
Truncation allows you to search for a root word with all of its different endings by placing a symbol at the end of the word. Symbols vary by database so check the help section on each database. Common symbols are:
! (exclamation mark)
? (question mark)
The computer will search for feminist, feminism, feminists, feminine, feminize
Most search engines have advanced search features or tips for better searches, allowing you to be more specific with your search and refine your search results. You can use the following search limits and more:
If the search engine does not have a separate advanced search screen, use the search filters that appear on the search results page (Google, Yahoo, DuckDuckGo, Google Scholar) or view the Help section for search tips (allintitle; site; filetype).
How many searches do I need to execute?
Doing separate searches for the different points or subtopics will allow you to find information for each part of your paper. If you are discussing both sides of a controversial issue, conduct a search for each side in unique searches. For instance, in discussing three proposals to improve the voucher system, you may want to search separately for each point you want to discuss.
Two cases in which separate subtopic searches are not recommended:
