Using Search Connectors and Commands

• All Boolean terms - AND, OR, NOT - are case insensitive and if used in the text box will be considered as Boolean operators (unless enclosed in quotation marks).
• For multiple search terms within a text box, the default operator is an “AND”. For example, Iran and Iraq, Iran AND Iraq, and Iran Iraq will return the same exact results set.
• To look for an exact match for a multi-term phrase, enclose all terms in quotation marks. example: "Iran and Iraq" will return documents with the exact phrase "Iran and Iraq"
• To connect a multi-term phrase to another search term via Boolean connecter use quotation marks. example: "Iran Contra" AND Iraq will return documents with the phrase Iran Contra and the term Iraq
• To find a document with words near each other, use the NEAR/n command. Default NEAR value is 100 words. Example: Iran NEAR/5 will return documents with the words Iran and Iraq within 5 words of each other.
• ALLCAPS command will return documents with the search phrase in all upper case letters. Example: ALLCAPS (epa) will return documents with the three letter acronym EPA in upper case letters.
• Quotation marks will return documents with the exact phrase within the quotation marks. Example: "Iran and Iraq" will return documents with the exact phrase Iran and Iraq.
• Use parentheses to group complex search phrases connected with Boolean connectors and other operators. Example: (("Iran and Iraq") AND (USA NEAR/5 China)) OR ((Syria NEAR/3 Hezbollah) AND ("Russian Arms Supplies")) will return documents that have satisfied the conditions in first double parentheses OR have satisfied the conditions within the second set of double parentheses.
• The query builder parses query terms from the left to the right.
• Non keywords (also known as stop words) include a, an, the, on, in, *, ?
• Mnemonics are as follows:
