Graphical user interfaces and methods for building Boolean queries and
viewing search results using search cells, combination cells, toolbar, and menu
bar. Search cells are movable within a workspace and contain a text field, facet
type designation, advanced button, and hit count. Categories are chosen using a
category walker. Combination cells, a Boolean combination of two or more selected
search cells, are also movable and contain a combine icon, hit count, and an expression
field. Boolean logic can be graphically depicted with the use of combination brackets.
Contents of combination brackets are controllable through use of movable graphical
pins between search cells. Alternatively, the Boolean query is depicted in a folder
tree hierarchy, where search folders are shown within combination folders, which
are represented as logical AND, OR, or MINUS folder icons. An applet in a browser
accesses a server through the Internet.
