Searching the CAB Thesaurus
Choosing the language
The CAB Thesaurus is available in eleven languages. Once a language is chosen from the drop-down list all searches and browsing will be in that language.
Browsing the thesaurus
From the Home page click "All terms A-Z" in the top menu. Then to browse alphabetically, click on "All" or a letter of the alphabet under "All Terms A-Z" in the central panel. Clicking on a term in the term list will display the term record.
To browse by term subject category or technical category, first click "Browse by subject / category" in the top menu, then click on "Subject Category" or "Technical Categories" to display appropriate lists of categories. Click on one of these categories to display a list of terms that belong to that category. Clicking on a term in the term list will display the term record.
On the term record display:
- Clicking on a related term will display its term record.
- Clicking on a subject category or technical category will list all terms within that category.
Search terms by entering the first few letters of the term or the entire term in the Search Thesaurus text box, then click the arrow or the "Search" button. When the "Search results" are displayed, clicking on a term will display the term record.
The following search options are available:
Select the language from the drop down list upon which the search will be performed.
Determines whether to look for terms which begin with the text entered or terms which contain the text entered.
Searching for 'plant' with "Search type" set to "terms begin with text" will find
- plant (industrial)
- plant analysis
- plant anatomy
- plant breeding
Searching for 'plant' with "Search type" set to "terms contain text" will find
- abortion (plants)
- acaricidal plants
- algicidal plants
- Alisma plantago-aquatica
Determines what information is displayed in the results:
- "simple term list" is an alphabetical list of the terms, one row per term
- "terms + relationships" displays the term record for each term. This search is slower than the simple list.
- "terms + hierarchy" displays the 2-way formatted hierarchy for each term. In this format, periods (".") denote narrower terms, and colons (":") denote broader terms. This search can be slow, depending on the number of levels each hierarchy has.
Terms per page
Determines how many terms per page to include in the results. A higher number will display more information, thus making it slower. However, a lower number might force you to click "Next >" in order to find the term.
Determines whether to search alphabetically for terms which are equal to or greater (alphabetically) than the text entered or whether an exact match is required. These two options apply only where the "Search type" is "term begins with text".
With the Search String equal to "qa" and "Search type" set to "term begins with text" and "Match terms" set to "Equal or Greater"
The result is:
Note that words beginning "qi" and "qu" are greater alphabetically than "qa".
- Qalyub virus
- Q-I relationships
- Qing Hai
With the Search String equal to "qa" and "Search type" set to "term begins with text" and "Match terms" set to "Exact prefix"
The result is:
In this example there are only two words that begin with "qa".
- Qalyub virus
Determines whether results should display all terms in the thesaurus that match the search criteria or only top terms. These two options apply only where the "Search type" is "term begins with text". A top term is a term that sits at the top of the thesaurus hierarchy. That means a top term does not have any Broader Terms. For example, the following is the Term Record for the top term "eukaryotes". Notice there are no Broader Terms, only Narrower Terms.
COM Common Name (Organisms)
P Plural Form
Related Term Broader
ON Organism Names
When "top terms" is chosen, the search will perform significantly slower.
Creating a search string using the Search String box
Clicking on an button will add the adjacent term to the Search String box. The search string can be extended by adding further terms. Once complete the search string may be sent to a search engine by clicking "Send to CAB Direct" or "Send to Google" or "Send to Yahoo". The search results are displayed in a separate browser tab. The "Send to CAB Direct" option will work only if your institution has a subscription to this service.
The Search String box is fully editable. A search string may be edited at any time.
If you want to clear the search string box, click on the "Clear Search" button below the box.
The search string can handle Boolean operators, such as OR, AND and NOT. The default operator is OR but that can be edited to something else. It is recommended that Boolean operators be typed in upper case.
When a term record is displayed, the "Send Feedback" option is shown on the top right of the screen. Clicking on this opens the default mail client on your computer, with the current (or first) term as the subject, and the predefined recipient firstname.lastname@example.org.
