How can you figure out the best way to search a new or unfamiliar journal database? Although many databases look different at
first, most have similar features. Understanding these basic features will improve the efficiency and effectiveness of your
searching. It will save you time and also will improve the accuracy and comprehensiveness of your searches. What you learn
with one database can be applied in most cases to other databases that you encounter. Below is a list of things to consider about
any database and some tips on how to determine the specific features of the databases you wish to use.
What is in the database?
Scope: What subject areas are being covered? What years are covered? What type of materials (journals, books, book chapters, dissertations, etc.) are included? Can you find a list of journals or other materials that are included in the database? Check for any links to “About this database” for the answers to these questions.
What does it search?
Can you search by keyword, subject, author, title of article or journal? What is the default search and how do you switch to other types? Clicking on “Help” should give you information about the various searches available.
|How does it search?|
Phrase versus Word searching
Determine whether the database considers multiple words as a single phrase or a combination of words connected by OR (any of the words), or AND (all of the words). Use OR searches to broaden your search. Use AND searches to narrow your search. Check to see what the default search is and also if other options are available.
Most databases allow you to search on a truncated (abbreviated) form of a word plus a wildcard. The wildcard must be directly next to the truncated word for this to work. Check to see what the truncation symbol is in the database. The most common truncation symbol is *(asterisk). Others include #, !, and $. For example, psych* will retrieve items on psychology, psychotherapy, psychotic, etc.
Controlled vocabulary/thesaurus searching
Some databases offer the option of searching by controlled vocabulary terms. These authorized terms describe topics in the database and are frequently collected in a thesaurus. Using the controlled vocabulary/thesaurus terms in your search ensures that items retrieved are specifically on the topic of interest. Check to see if your database has an online thesaurus to determine the best controlled-vocabulary terms to use for your search.
What do I do if I get too many results?
Are there any limit options?
Most databases allow you to narrow your search by selecting specific dates, language, and publication types. Some databases also allow you to restrict your search to titles for very precise results.
Can you combine searches or add more concepts to your original search?
One quick way to reduce your results and focus your search is to add one or more additional concepts to your search. See if you can type more terms into your search box, or if you need to modify your search in another way. Also, is there a “Search History” feature available? If so, you may be able to combine some of your previous searches into a new one that should reduce your results and focus your search. Also try focusing your search by using controlled vocabulary terms as described in the “How does it search?” section above.
What do I do if I get too few results?
The more concepts you combine in a search, the fewer results you are likely to retrieve. If you get little or no results from your search, try eliminating some of your concepts, limits, or modifiers.
Some databases offer a “Related Articles” or “Find Similar Results” feature that enables you to expand your search. If you find only one or two articles on your topic, see if this feature is available. Clicking on a Related Articles link will allow you to retrieve more articles similar to the one with which you started.
Cited reference search
Another way to expand your results is to do a “Cited Reference Search” on any relevant article you might have. This feature is available in databases offered through Web of Science. When you perform this type of search, you will retrieve articles that have cited the original article. You can use a cited reference search to find more up-to-date material on your topic, since retrieved material from this type of search will be more current than the original article.
How do I locate material from my search?
Many databases allow you to check if ASU library subscribes to the material you retrieve in your search. For many databases to which the ASU Libraries subscribe, electronic or print availability can be determined via the Find[at]ASU button. Click on this link to access the electronics versions of any material provided by ASU Libraries in that format or to find the location (call number) for the print version in the library.
How do I print, email or download my results?
Most databases offer the option of printing your results. Others also allow for e-mailing and/or downloading your results. Once you have selected all your items, click on the print, e-mail, or download option and follow the on-screen directions. You usually can customize the results to include abstracts and/or subject terms. To download into bibliographic management software, such as EndNote or Zotero, check to see your options and format your results appropriately.
