Match All Words
More than one word in the same document. For example, when searching for oil AND gas, all documents containing both the words oil and gas will be displayed.
Match Any Words
Either word in a document. For example, when searching for oil OR gas, all documents containing either oil or gas will be displayed.
Boolean Search
When typing in the "and" operator between two words (e.g., "oil AND gas") you are searching for all articles containing both of the words. When typing in an "or" operator between two words (e.g., "oil OR gas") you are searching for articles containing either of the words.
When searching for the first term without the second term in a document. For example, oil AND NOT gas, will display all documents with the word oil but not gas.
A more complicated search can consist of several terms in the same document, but not others close together. For example, when searching for (oil OR gas) AND NOT (abandon NEAR well), you are searching for documents containing the words oil or gas but not the word abandon near the word well.
Use double quotes (") to find exact phrases. For example, "oil and gas" will find documents with the exact phrase, but will not display documents where the phrase is not exactly as typed.
