Search Help


The information on the web site is stored in a database of records of research projects. Each database record is divided into fields, or categories, of information, such as project title, sponsoring organization, and principal investigator. When you use the search form, you can specify which field(s) to search and which word(s) to look for within the field(s). Use any combination of field critera below to better narrow the search results.

Search Techniques
Use the below search techniques within the "Title" , "Title, Abstract, and Index Terms", or "Contract/Grant Number" fields to refine your results .

Quoted Phrases
Adjacent words are NOT assumed to be a phrase. Quotes must be used to identify a search phrase. The search term "traffic signal timing" retrieves only records where the three words appear together and in that order.

Search terms are not case sensitive. CHICAGO, Chicago, and chicago all retrieve the same records.

Truncation/Wild Card
Type an asterisk (*) after a partial word to retrieve all variances. Driv* finds drive, driver, and driving.

OR Operator
To broaden your search, use the or operator. In the Keyword field, for example, enter emission* or air quality to find either term.

AND Operator
To focus or narrow your search, use the and operator. Searching the Abstract field for asphalt and laboratory, for example, requires that both terms be present.

AND NOT Operator
To exclude a term from your search, use the and not operator. Searching the Abstract field for rail and not transit, for example, requires that transit not be present.
