Abstract
A method for automatically updating a filter logic expression representing a Boolean filter comprising a plurality of search conditions is disclosed. The method includes receiving a first indication to remove a first search condition from a condition list comprising search conditions. Each search condition is associated with an identifier and the first search condition is associated with a first identifier, and the search conditions are listed in sequential order according to the associated identifier. In response to receiving the first indication, a second search condition associated with a second identifier that sequentially follows the first identifier is identified, and the second search condition is reassociated with a third identifier that immediately precedes the second identifier. A filter logic expression comprising a plurality of identifiers and operators and representing a Boolean filter is then modified by automatically replacing any reference to the second identifier with the third identifier.
