## Lesson Three

Basic Searching in Electronic Databases

### Introduction to the Basic Search

• Congratulations! In the previous section you learned how to access the electronic databases. It is now time to put that knowledge to work.

• In the following sections, you will learn how to conduct a basic search using 2 of the database collections: EBSCOhost Web® and ProQuest®.

### What is a Basic Search?

• A basic search is simply what it says: a basic, no-frills search that allows you to enter search words or phrases related to your search.

• A basic search is also known as a simple search.

• Most basic searches will allow the use of Boolean operators.

• The words AND, OR, or NOT are Boolean operators. The addition of any of these three small words to a search can improve your chances of an "on-target" search.

### What is Boolean Searching?

• As mentioned earlier, AND, OR, and NOT are known as Boolean (or logical) operators.

• Why are they called "Boolean" operators? How can these words improve a search?

• George Boole was a mathematician who studied theories of sets. Boolean logic refers to his system of combining sets.

• AND, OR, or NOT connect words in a search. The Boolean operators each perform a specific function.

### Review: The AND Operator

• And tells the database to look for all of the words in a search. All of the words must appear in the results of the search.

• This can be helpful in limiting a search. For example, a search for "violence and music" would find articles that containing both the words "violence" and "music". One term would not appear without the other term.

### Review: The OR Operator

• Or tells the database to look for any of the words in a search. Any or all of the words can appear in the results of a search.

• This can be helpful in looking for articles containing a search term that has several synonyms. This can help broaden a search. For example, a search for "aged OR elderly" would find more articles than a search using only one of the terms.

### Review: The NOT Operator

• Not tells the database to only bring up results that contain the first search term, not the second word connected by the NOT operator. NOT is an eliminator.

• For example, a search for "candy NOT fudge" would look for articles containing the word candy. If the word fudge appeared in an article, the article would not be listed in the results.

### Using Boolean Operators

• Now look at the searches that will follow. Decide whether the Boolean operator is broadening, narrowing, or excluding parts of the search.

### Using Boolean Operators

• Doctors Or Physicians. Is the Boolean operator…

• Narrowing a Search

• Excluding Parts of the Search

### Using Boolean Operators

• Copyright Infringement NOT Recording Industry. Is the Boolean operator…

• Narrowing a Search

• Excluding Parts of the Search

### Using Boolean Operators

• The answer is Excluding Parts of the Search.

### Using Boolean Operators

• Advertising AND Television. Is the Boolean operator…

• Narrowing a Search

• Excluding Parts of the Search

### Using Boolean Operators

• The answer is Narrowing a Search.

### How to Locate a Scholarly Journal Article From an Online Database

• NOTE: Scholarly journals were previously reviewed in the Information Literacy section of the tutorial.

• You may wonder how to locate scholarly and peer-reviewed journals using electronic databases. After all, the publication cannot be physically held in your hands. The publication may also be formatted differently for Internet viewing.

• Many database publishers realize this.

### How to Locate a Scholarly Journal Article From an Online Database

• Therefore, many electronic databases contain a feature that the user can select to limit the results to scholarly (peer-reviewed) journals. This feature is often found on the Basic Search screen.

• For example:

• The ProQuest Database Collection has a feature that limits the results to "Scholarly journals, including peer-reviewed."

• EBSCOhost also allows the user to limit results by "Scholarly (Peer Reviewed) Journals."

### How to Locate a Scholarly Journal Article From an Online Database

• But... what if the database that you are using does not have a limiting feature?

• There are several options that you have:

• Use the criteria for scholarly journals to determine whether the publication is scholarly or a popular magazine.

• Read the description of the database that you are searching. The database may be scholarly in nature.

• Read the description of the publication title. Publications will indicate whether they are scholarly or popular in nature.

### ProQuest® and the Basic Search

• As mentioned earlier, ProQuest® consists of six different databases: ABI/Inform Research® (business topics), Career and Technical Education® (vo/tech topics, including nursing and allied health), Alt-Press Watch® (coverage of the alternative press), and Social Sciences (Criminal Justice Periodicals).

• The default screen for ProQuest® is the Basic Search screen.

### Let's Try a Basic Search!

• Now it is time for you to perform a Basic Search in ProQuest®.

• To start, click here to go to the Library's web page.

• From the Library web page, go to the ProQuest® databases.

• (NOTE: If you do not know how to open the ProQuest® databases, please go back to the section of the tutorial that explains how to access the electronic databases).

### Let's Try a Basic Search!

• You may need to minimize the ProQuest® screen as necessary in order to read the instructions on this screen.

• From the Basic Search screen, type in your search terms.

• Let's say that you have been given an assignment requiring you to write a paper about electronic commerce.

• Type electronic commerce in the Basic Search box.

• Also, you are probably interested in retrieving full-text, so...

• Click the box beside Full text articles only.

• Click the SEARCH button.

### Let's Try a Basic Search!

• Here’s how your search should look:

### Basic Search Results

• How many results did you retrieve? The last time we searched, we found approximately 38,000 articles on electronic commerce. (NOTE: You should have found at least that many articles).

• That's quite a few articles!

### Basic Search Results

• It is unlikely that you need or want to look over that many articles. Some of the articles may be irrelevant to your search.

• There are limiters that can be used to narrow down your search.

• For example, if the assignment requires only scholarly articles, you could narrow down your search by clicking the scholarly journals tab.

• This will re-run your search looking only for full-text, scholarly journal articles.

### Basic Search Results

• Here are the results of the search that we ran looking for full-text, scholarly journal articles on electronic commerce. 1455 articles were found the last time we searched. Note that the SCHOLARLY JOURNALS tab is highlighted. *Image courtesy of ProQuest®.

### Refining a Search

• The previous search resulted in a large number of articles.

• You can further refine (or limit) the results with the use of the Boolean operator, AND.

• In contrast, you could broaden your search by using the Boolean operator, OR, along with e-commerce, a synonym of electronic commerce. (Example: electronic commerce OR e-commerce).

• As mentioned above, the use of AND will limit your research and further narrow your search.

### Refining a Search

• You would also need to consider other search terms that you are interested in.

• Let's say you are interested in scholarly journal articles about spam in relation to electronic commerce.

• Refine your search by adding spam to the full-text, scholarly journal search for electronic commerce.

### Refining a Search

• How many articles did you find? You should not have found a great number. We found two articles! Try other searches on your own using the ProQuest® databases. You will find that ProQuest® can be very useful for research.

### EBSCOhost® and the Basic Search

• As mentioned previously, EBSCOhost® contains over 27 databases. These databases cover a wide variety of topics.

• The default screen for these databases is the BASIC SEARCH by KEYWORDS.

### Try a Basic Search Using EBSCOhost®

• Now it is time for you to perform a BASIC SEARCH in EBSCOhost®.

• To start, click here to go to the Library's web page.

• From the Library web page, go to the EBSCOhost®.

• From the EBSCOhost® screen, click EBSCOhost Web®. This launches the database selection menu.

### Try a Basic Search Using EBSCOhost®

• The default screen is BASIC SEARCH by KEYWORD.

• In the SEARCH box, you will type in your search terms.

• Let's say that you are interested in finding articles on the effects of September 11, 2001 on the business world.

• Type September 11 into the search box and click SEARCH.

### A Sample Basic Search

• You will notice that your search retrieves a large number of items -- over 20,000 articles in the database have the phrase "september 11" somewhere in the record.

• Some of the articles will have full-text, some will not.

• Click on the title of an article to bring up more complete information.

### A Sample Basic Search

• Look at several articles until you see one that includes *SEPTEMBER 11 Terrorist Attacks, 2001 as a SUBJECT TERM.

• Click on September 11 Terrorist Attacks, 2001 and the database will perform a new search.

• Notice the difference in the number of items that your search retrieves -- it should be about half as many items as the first search found.

• This search helps to illustrate the difference between a keyword search and a subject search.

### Subject Terms Versus Keywords

To review:

• What is a keyword search?

• A keyword search looks for your exact term in article titles, abstracts, and subject fields. The term may or may not be the main focus of the article.

### Subject Terms Versus Keywords

• What is a subject search?

• A subject search looks for subject headings that match. The subject is the main focus of the article.

### Subject Terms Versus Keywords

How to use keyword and subject searches:

• A keyword search is an excellent first search strategy. Often, you may find what you need with a keyword search.

• However, a keyword search is a broad search. Not all of the results that you retrieve will be relevant. Some will be off-topic because your search term is a common word that is found within the article or abstract, but is not the focus of the article.

• A subject search is a search that is focused on the topics covered in an article. This means that the articles you find will be more relevant to your search.

### Refining a Search

• Continuing with our previous example, we still have over 10,000 references on the subject of the September 11 attacks.

• It is unlikely that you want or need to look over that many references.

• You can refine this search by clicking the small LIMIT YOUR RESULTS tab near the top of the search screen.

### Refining a Search

• A number of options are given to limit the number of items that are retrieved.

• Click on FULL TEXT and then click UPDATE RESULTS.

• The system will re-run your search strategy, limiting the results to articles that are available in FULL TEXT.

### Refining a Search

• You will still have a great many items, so...

• Go back to LIMIT YOUR RESULTS.

• Click on SCHOLARLY (PEER REVIEWED) JOURNALS.

• Click on FULL TEXT.

• Run the search again.

### Refining a Search

• Note that, in refining the search, you have not changed your search strategy, but you have limited your retrieval to full-text articles from scholarly journals.

• Congratulations! You have conducted a search in EBSCOhost®!

• There are other basic features that can be very helpful in using a database.

• Most databases will allow you to e-mail results (usually the citation and abstracts, but in some cases the full text of the article can be e-mailed).

• Some features are unique to a particular database.
