Using the Right Terms
When searching in databases, how do you know that you are using the right terms. If you come up with zero results, then you know that you have used at least one term that should be changed to another term that is similar in meaning. It could mean the difference between zero results and many results.
What are index terms?
Index terms are controlled vocabulary terms used in database records to make searching easier and more successful. By standardizing the words or phrases used to represent concepts, you don't need to try and figure out all the ways different authors could refer to the same concept.
Why is a controlled vocabulary essential for searching?
With the wide variety of concepts and vocabulary used in academic literature. Search and retrieval of records about specific concepts is virtually impossible without the controlled vocabulary of a thesaurus. This controlled vocabulary provides a way of structuring the subject matter in a way that is consistent among users
Controlled Vocabulary Thesauri
The ERIC Thesaurus is a leading authority on the language used in the field of education. It is a controlled vocabulary with nearly 12,000 terms, including more than 4,500 descriptors and 7,000 synonyms. Descriptors from the Thesaurus are assigned to each of the 1.9 million records in ERIC to describe the main subjects of the content. Synonyms point searchers to the preferred term, or descriptor, in ERIC.
General Thesauri
Search modes offer different ways to conduct a search and find information.
Search Mode | What it Does |
Keyword/Phrase |
Searches for terms that are in proximity to one another.
A record will be returned only if all the words searched are found within the same field, such as title, subject, or abstract. There is no proximity across fields or subfields.
|
Find all my search terms |
Automatically searches with Boolean “AND” between all search terms.
|
Find any of my search terms |
Automatically searches with Boolean “OR” between all search terms.
|
SmartText Searching |
You can copy and paste large chunks of text into the search box.
SmartText Searching technology reduces the text entered to the most important search terms based on term frequency (TF) and inverse document frequency (IDF) , and then creates a weighted Boolean query for search execution. |
Natural Language (DEFAULT) |
Natural Language Search (NLS) mode is an advanced search feature that allows users to query using everyday language. Instead of relying on complex keywords or Boolean operators, NLS enables users to form searches in a more conversational manner. |
Citation Chaining: Finding the Original Research
Citation chaining is a research technique where you review sources referenced by an original source, thus creating a 'chain'
How to Chain
If the article is in the database, it will display in the search results list.
To learn more about how citation chaining works, watch the video below.
How Library Stuff Works: Citation Chaining
Video Summary
This video provides an overview of the research tool citation chaining, including its benefits and limitations.
Expanders are search settings that broaden your results by adding related terms, going beyond the use of the OR Boolean operator.
Expander | What it Does |
Apply Equivalent Subjects |
Select this option to utilize mapped vocabulary terms to add precision to unqualified keyword searches.
|
Truncation |
Allows you to enter the root of a search term and replace the ending with an asterisk (*) This allows the database to find all words with the same root.
|
Wildcard Symbol |
Can insert this symbol (?) anywhere within a search term, and it holds the place of a letter/character. It matches exactly one letter/character, helpful for alternative spellings of words.
|
Limiters are ways, other than using the Boolean operators AND or NOT that will make your search results smaller.
