Exact phrase searching limits your search to multiple terms in the precise order specified. For example, searching for "south east asia" will only find results that include those three words side by side and in that order.
You can specify exact phrase searches in any of the free text search boxes by enclosing the phrase in double quotes " ". For example, when you enter "Harry Truman" in the main keyword search box, your results will only include results where the words Harry and Truman appear together, in that exact order. In this example you will not retrieve Harry S. Truman.
If you enter an operator inside of the double quotes, then the operator is treated like a regular word, and the search is based on an exact phrase match. For example, if you enter the exact phrase "Harry and Truman", your search will include results where the three words Harry and Truman appear (all together and in that order).
If you enter more than one exact phrase, and you do not include an operator, then your search will include results where both exact phrases are found. For example, if you enter "Harry Truman" "Jackie Kennedy", your search will include results where both Harry Truman (together and in that order) and Jackie Kennedy (together and in that order) appear. However, if you enter "Harry Truman" OR "Jackie Kennedy", your search will include results that have either Harry Truman or Jackie Kennedy or both.
If you enter an exact phrase plus one or more other words, and you do not include an operator, then your search will find results that include both the other word(s) and the exact phrase. For example, if you enter Truman "Jackie Kennedy", then this is interpreted as Truman AND "Jackie Kennedy".
