Polymer Library: Searchable Fields


The RAPRA Thesaurus is used to index the Polymer Library database subject field. Subject terms are found in the subject field and this field is part of the searchable fields table to the right. Subject terms are also commonly known as descriptors, controlled vocabulary, and sometimes classification terms.

The thesaurus allows you to find subject terms to narrow or broaden your search and is available from the Advanced and Command Line Search. If you want to run a search on a subject, but you do not know what term to use, use the thesaurus to search the controlled vocabulary. The display will give suggestions on the appropriate subject terms to add to your search.

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 using the Find button. 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 (adding additional search fields and terms if needed).

Look Ups and Browsable Indexes

Polymer Library offers several 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: author, publication, subject, and company/organization. For a description of these fields, please see the Fields codes link 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.

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, select Contains or Begins with, click Find, 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.
