The quest for improving retrieval performance has led to the deployment of larger syntactical units than just plain words. This article presents a retrieval experiment that compares the effectiveness of two unsupervised language models which generate terms that exceed the word boundary. In particular, this article tries to show that index expressions provide, beside their navigational properties, a good way to capture the semantics of inter-word relations and by doing so, form an adequate base for information retrieval applications.
