This section describes how to search for terms in the thesaurus:

To access Thesaurus Search, select Thesaurus > Thesaurus Search.

The following page is displayed:

To start, select a thesaurus from the drop-down box on the left.

You can only search and work with one thesaurus at a time. A thesaurus must have been defined in the Creating a thesaurus section for it to appear in this list.


Display options

Once you have selected a thesaurus to work with, the display panel is populated with terms, depending on the default display defined for this thesaurus. This is defined in Creating a thesaurus.

It is possible to change the type of display of terms by selecting one of the three tabs that are available.



Displays top level terms. You can click on a term and expand that segment of the hierarchy (if there is a + symbol next to it), or you can click on "Expand All" to see the entire set of terms and child terms.


Displays an A-Z listing to select terms by alphabetical sorting. You can click on a term and expand that letter (if there is a + symbol next to it), or you can click on "Expand All" to see the entire list of terms.

Results Only

Terms are only displayed here if you have done a search:
