About the Thesaurus Term Search
The NCJRS Abstracts Database Thesaurus Term Search allows users to search for materials located in the Abstracts Database using an official NCJRS–controlled vocabulary. This controlled vocabulary is used to assign relevant indexing terms to the documents in the NCJRS collection. These indexing terms are located at the bottom of each abstract record in the Main Term and Index Term fields. See the record below for an example of "Main Term" and "Index Term."
Starting the Search
To begin a Thesaurus Term Search, 1) use the alphabetical term list, OR 2) use the keyword search box. The thesaurus search looks only for terms listed in the Title field of the abstract record.
Browse and choose search term(s) from an alphabetical listing of the NCJRS–controlled vocabulary. This search allows users to match exact term(s).
Browse the alphabetical list of thesaurus terms by:
- Selecting the Browse alphabetical term list link,
- Checking the box(es) next to the term(s) relevant to your search.
Enter a keyword into the search box and select the "Go" button.
This search allows for possible matches and terms related to the keyword(s).
NOTE: When using the keyword search box, a keyword is automatically selected as a search term if it is an exact match. At all other times, users must manually select the search term(s).
Selecting a Term
From the results provided by browsing the thesaurus term list or the keyword search entry:
Check the box next to the appropriate thesaurus term(s).-- OR --
Expand a term by selecting the term to view additional information and other related terms.
Expanding a Term
To expand a term (view additional information and related terms), select the term text. Text will display underlined when cursor is pointed at the term.
When a term is expanded, the results page will contain information specific to that term. If applicable and available, additional entries (e.g., Scope Note, Used For, Broader Term(s), Narrower Term(s), and Related Term(s)) will be provided.
The Scope Note entry defines or limits the specific use of a term. The Used For entry displays other concepts represented in the NCJRS system by the selected term. Broader Term(s) represent the higher, more general levels of a term's relationships, whereas Narrower Term(s) represent the lower, more focused levels. The Related Term(s) entry performs two functions: It provides alternative search terms and clarifies the scope of the expanded term.
Adding More Terms
To add more terms to a search, select the “Add Terms” button and search for more terms as noted above.
Review Selected Terms
Selected search terms display for review.
After one or more terms have been entered, the “View Selections” button will display next to the Go button of the keyword search option. To view all selected terms from the Thesaurus Search page, select the “View Selections” button.
Selecting the “View Selections” button will display all selected terms along with term conditions to Finalize the search.
Begin New Thesaurus Term Search
All of the selected terms can be cleared and a new Thesaurus Terms Search begun by selecting the "Begin New Thesaurus Term Search" button.
After selecting and reviewing the term(s), select the “Finalize Terms” button. If the “Execute Search” button is chosen from the search results screen and the term conditions have not been entered, the Finalize Terms screen will display.
After selecting the “Finalize Terms” button, a list of all the selected terms will appear.
- Actions: add more terms, deselect search terms, clear terms to start new search, or execute the search.
- Apply search conditional choice:
- Choosing ALL between the search terms means that those terms must be present as indexing terms in the record(s) returned.
- Choosing ANY means that any of the selected terms may be present, but not necessarily all of the terms.
Note: In general, ALL will reduce the number of hits returned but give a more precise search; ANY will increase the number of hits returned but will not offer as much precision.
- Select the “Execute Search” button to initiate the thesaurus search based on entered criteria.
