The search engine searches the entire record (all fields) for terms entered in the KEYWORD search box. It is possible to conduct a complex search in the KEYWORD search box using Boolean Operators and nesting. PLEASE NOTE: The use of Boolean Operators, nesting, and phrases is ONLY possible in the KEYWORD search box.

BOOLEAN OPERATORS are the terms AND, OR and NOT. When the term AND is placed between two words, the search engine searches for articles containing BOTH the first and second word. Example: Quaternary AND beetle. When the term OR is placed between words, the search engine searches for articles containing EITHER the first or second word, or both. Example: petroleum OR oil. The term NOT is useful for eliminating irrelevant information. The search engine searches for records containing the first word BUT NOT containing the second word. Example: North Dakota NOT survey.

By using parentheses, search strings can be "NESTED" similar to mathematical formulas, resulting in complex, sophisticated searches. For example: (("white river" or brule or chadron) and (stratigraph or sediment or lith)) not lignite. Quotes are used to denote a phrase. See below for an explanation of TRUNCATION. In the proceeding example, the search engine looks for any records containing the phrase "white river" or the words brule or chandron. It also looks for any records containing the words stratigraphy or stratigraphic, etc. or sediment or sedimentary or sedimentation, etc. or lithology or lithologic. Then it will return any records that contain at least one word from the first group and at least one word from the second group, as long as the word "lignite" is NOT present.

TRUNCATION: The search engine automatically places wildcards at each end of a single term or phrase. For example, if you type "anders", it will match both "Flanders" and "Anderson".


In addition to searching the entire record by using the KEYWORD box, it is also possible to limit the search by requiring words to exist within particular fields.


In any of the below fields, truncation is supported for single terms, or at the beginning or end of a phrase.
