Researchers have identified a significant weakness in dense retrieval models, where their ability to follow relational instructions falters when the direction of the relation is reversed. A new diagnostic tool called SwitchIR was developed to test this, contrasting constraint shift and explicit filtering with relational flips. The study found that while models perform well with lexical cues, they struggle when relevance hinges on directional relationships, often failing to overcome inherent biases in the query-document pairs.
