A new approach to index organisation in inverted data bases, the filter organisation, is presented, which seems to be superior to classical organisations for a large class of applications. The general advantages of inverted data bases, namely fast retrieval and simple implementation of set theoretic operations, are preserved. Major improvements are obtained concerning storage requirements of the indexes and update behaviour. By the filter concept high stability of the whole index is obtained.
