The Boolean Form
In addition to the Quick/Number search form, Premium and Unlimited subscribers have access to the Boolean and Advanced search form options:
The Boolean search input form is designed for new searchers who may not be entirely comfortable with constructing search logic. This page allows users to create a combination string with up to four different search terms connected by Boolean operators. Drop-down menus allow users to select the field of search for each term, and the desired Boolean logic to connect the terms. Users can select the collections to search in, including specific countries from the INPADOC file. Date limitations (by publication, filing or priority date) can also be applied here.
