Advanced Search

Text Field Searching

These rules apply to any plain text field on the advanced search form.

  • For an exact match, enclose a phrase within quotes: "traffic signal"
  • For a wild-card search, use an asterisk (*) after a partial word. Note that you may also truncate at the front of a term or use more than one asterisk for a term but the terms will not be highlighted in these cases.
  • For a boolean search, use OR, AND, or NOT between words or phrases.
  • A nested search may be performed by enclosing term(s) within parentheses.
  • Search example: (plow* OR salt*) AND "snow removal"

Keyword Field

This field searches all of the indexed fields in TRID which include title, abstract, notes, index terms, subject areas, record accession numbers (both TRIS and ITRD), and authors.

Title Field

Enter one or more terms from a title or the exact title to search on a publication title.

Serial or Conference

Enter one or more terms to search for records from a serial or conference.

Issue Number

Enter one or more terms to search by TR News issue number or TRR number.

Subject Areas

Click the field or use the down arrow to select a TRB subject area to limit search results by a specific transportation mode, function, or activity. You may also start typing to filter the list, then use the arrow keys or highlight with the cursor to select a subject area. Multiple subject areas may be selected; simply repeat the process as for selecting the first subject area. If you select multiple subject areas, you can switch between "or"/"and" Boolean logic for your selections by selecting the appropriate radio button.

*Note that ITRD Subjects are searchable in the keyword field


Enter complete or partial terms to search for report, contract or grant numbers.

To search for multiple terms, use OR to separate search terms.

Index Term

Begin typing an index term. If the term is from the Transportation Research Thesaurus (TRT), matching terms will appear in a drop down list from which you can select terms. More than one term may be selected; in this case the default Boolean operator is OR.

Uncontrolled terms and ITRD Thesaurus terms do not appear in the drop down list but are still searchable in this field. To search uncontrolled terms or ITRD thesaurus terms, simply enter the terms on which you wish to search and press Enter.

To use Boolean logic and/or wildcards, simply enter the query without selecting any terms from the drop down list.


Enter a person's last/family name and first/given name or initial to search among authors and editors. You can use wildcards and Boolean logic to search across all matching names, including first names.

Note that a query for Smith, R* will return results for 'Smith, Robert,' 'Smith, Richard' and authors 'Smith and Robert' or other last/family and first/given names that begin with the letter R. It will not return results for 'Smith, Bob'. Please keep in mind that due to differences in indexing practices among the various contributors to the TRID Database, some records contain only first/given initials rather than full names.

Result Type
