    Abstract
    After introducing types of records, queries and text processing options, the features needed in software for phrase processing are identified and different approaches in current text retrieval research in the Text Retrieval Conference (TREC) projects are enumerated. Then follow eight observations on issues in phrase searching relating both to practice and to research, giving the authors' selection of crucial and controversial issues, supported by 21 references
