A method provides a tool, which enables a user to review or examine filter conditions set based on input forms in an easier manner. The method generates a filter condition tree view for display to the user. The tree view represents the filter conditions as set by the user in one or more input forms. The tree view is a particularly simple and efficient way of displaying the filter conditions set by the user, thereby making it easier for the user to check at a glance which conditions actually have been set. The user can not only set filter conditions to be linked by a Boolean AND, which are the filter conditions input into a single input form, but also the user can input filter conditions to be linked to other filter conditions by a Boolean function, e.g., a Boolean OR. This is attained by providing the user with multiple input forms, where the filter conditions set in one of the forms are linked to the filter conditions input in another of the forms by a Boolean OR.
