To search for records whose content contains all entered terms, put the word AND between each term. For example, Germany and Poland and Russia will return records whose content contains all of the terms Germany, Poland and Russia. By default, all entered terms are 'ANDed', i.e., Germany Poland Russia is equivalent to Germany and Poland and Russia.
To search for records whose content contains a phrase, include the words of the phrase between quotes ("). For example "World War II" will return records whose content contains the phrase "World War II". Using the All Text field on the Advanced Search page, phrases can also be 'ANDed', 'ORed' or 'NOTed' with other terms and phrases. Note that you have to type the operators 'OR' and 'NOT' in ALL CAPS.
Complex searches can only be performed from the All Text field on the Advanced Search page. Note that you have to type the operators 'OR' and 'NOT' in ALL CAPS.
To search for records whose content contains any of the entered terms, put the word OR between each term. For example, Germany OR Poland OR Russia will return records whose content contains any of the terms Germany, Poland, or Russia.
To search for records whose content does not contain some of the entered terms, put the word NOT before those terms. For example, Germany Poland NOT Russia will return records whose content contains the terms Germany and Poland and not the term Russia.
Parenthesis, (), can be used to create complex search expressions. For example, Germany and (Poland OR Russia) will return records whose content contains both terms Germany and Poland or both terms Germany and Russia. Another example is "concentration camp" NOT (Auschwitz OR Terezin), which returns records whose content contains the phrase "concentration camp" and not the terms Auschwitz or Terezin.
