In some of the EBSCOhost databases, you will see a Thesaurus option on the horizontal black bar at the top of the screen. Searching for the thesaurus term for a topic will retrieve papers on that topic even if different authors have used slightly different terminology to describe the topic in their papers.
To use the thesaurus (this example uses the MLA Thesaurus):
You will see an alphabetical index of thesaurus terms, and synonyms for thesaurus terms, that are used in the database. You can click on the blue thesaurus term links to see related terms.
The thesaurus terms are arranged in a tree structure. Select a thesaurus term to see any:
Use the checkboxes to the left of the thesaurus terms to select any that you would like to include in your search.
Once you have selected any relevant thesaurus terms and Explode options, click on Add (just above the list of thesaurus terms) to add the selected terms to the search box. The default is to link any terms you have selected with the search operator OR, but you can use the drop-down menu to change the operator to AND, or NOT, if you wish.
Your selected terms will be added to the search box near the top of the screen. Click on Search. Your search terms and number of search results will appear as a line in the Search History / Alerts section beneath the search boxes on the Advanced Search screen.
Each thesaurus is database-specific. If you are using the thesaurus search options, it is best to search one database at a time, rather than cross-searching multiple databases.
