Abstract
Designers use negation to describe: (1) design problems; (2) contradictory ndings; and (3) unlikely root causes. An example negation is no signs of engine failures due to fuel exhaustion. Designers should be able to search for negated information in the same way as searching for confirmed information. For example, the following query is useful for designers carrying out a root cause analysis Find engine failures that were not caused by fuel exhaustion. Current search engines provide only limited support for negation nding. Using a search symbol such as `
