As you read and search, keep track of the vocabulary you encounter.
Terms and definitions vary by field. You will likely find your repertoire of key words expanding as you get deeper into your search. Keep track of synonyms, technical vocabulary, discipline specific terms--they often come in handy, particularly if, as sometimes happens in this course, you go on to do more advanced research on the topic in future classes.
Crime; criminology; criminal justice; criminal law; justice; prisons. Some terms, like "law," are so broad that they produce what can be an overwhelming number of search results. You may need to add in additional keywords to narrow searches. Other terms, like "order," can be used in many different contexts and therefore can produce widely disparate results.
Tip: if you locate some search results that seem relevant, look carefully at the terms and subject headings used to describe them. Use those terms in your next searches.
This document suggests a good method of crafting effective keyword searches:
Boolean Searching uses a combination of terms to search an online database. A Boolean search can either expand or narrow the results of your search. It is a kind of set theory.
This kind of searching is going on behind the scenes to some extent in almost any website or database you search whether you know you are doing it or not.
When you type a series of words such as
pets dogs hounds terriers poodles
It is most likely interpreted at the site as pets AND hounds AND terriers AND poodles
A database would interpret this as needing to include ALL of these terms. It might be a very narrow search.
You might really mean:
pets AND (hounds OR terriers OR poodles)
Pets becomes set one and (hounds OR terriers OR poodles) is set two.
In this case the database will
"AND" always narrows a search, "OR" always broadens it.
You can also use "NOT" to narrow a search further.
AND OR and NOT are also referred to as "operators."
pets AND (Hounds OR terriers OR poodles) NOT cats
"NOT cats" becomes set three.
Now the overlap will only include articles that DO NOT include the term cats.
This is a visulation--the area of the circles that overlap will be your results.
You can truncate your terms using an asterick * (Some databases may use a ? or another symbol, but * is the most common)
dog* (will also retrieve dogs, doggy, doggerel)
exist* (existent, existing, existence)
Think about your truncations before you truncate:
Rom* could be romance, rome, roman, romany, romantic, romperroom, and so on ... too many words too different one from the other to be useful.
It might be better to type (rome OR roman) or (romance OR romantic) or ("romance literature" OR "romance language")
Quotations and phrases
when searching an exact phrase, such as the title to an article or book, or two words that you always want together place them within quotation marks:
Facets are options at most databases to narrow your search further. You may see:
