A thesaurus is an alphabetical listing of all the subject terms in a single database, used to classify and organize information for that database. The thesaurus shows relationships between terms such as synonyms or related terms, and hierarchical arrangements such as broader terms, or narrower terms. Most ProQuest databases have an associated thesaurus. By adding thesaurus terms to your search, you can broaden or narrow your search, or find related words to further explore your subject of interest.
To use the thesaurus, select the Thesaurus link from the Advanced or Command Line Search, then browse or search for subjects containing the word or beginning with the word. Mark the items that you would like to search and then select the appropriate Boolean operator to combine your items. Click the Add to search button and your terms will be placed into the search form. From there, run your search to include the subject terms. You can also combine terms you find in the thesaurus with your current Advanced or Command Line search.
In addition to the all encompassing subject field, there is also a separate subject field for company/organization, person, and location. These are also included in the searchable fields table to the right.
You can also find additional Thesaurus help from our Thesaurus help file.
ProQuest databases offer up to seven Look ups or browsable indexes, so you can easily find spelling or format variations of, for example, an author's name or a journal title. You can find the Look up links in the advanced search page and they are available for the following searchable fields (dependent on the selected ProQuest database(s)): author, publication, subject, company/organization, person, location, and NAICS. For a description of these fields, please see the searchable fields table to the right.
Note: Look ups are also available from the Command Line search (through the Look up terms link).
To use and locate a Look up or browsable index, select the field from the advanced search pull-down menu. If a Look up is available, under the search row you will see a link to the Look up. Some databases will display their Look ups and browsable indexes above the Source Type field in the advanced search page.
Select the Look up link and then you will see a browsable and alphabetical index for that field. There are some indexes that will not display an alphabetical list before searching for the term, rather you will have to enter a term first, and then the alphabetical list of matches will display.
Once you locate the index term that you would like to add to your search, mark the item, and then click the Add to search button. The index term will now appear in the advanced search form along with the appropriate pull-down menu selection.
