    Abstract
    Compares and contrasts online searching on DataStar using the 'classic' command language, with access via the more recent Web interface (DataStar Web). The search functionality of the 2 interfaces is not identical, although both use the same retrieval software and access the same databases. Many of the differences affect retrieval effectiveness and may trip up novice and experienced searchers alike

    Abstract
    Considers 2 non-Boolean searching systems available on commercial online systems. QUESTQUORUM, based on coordination level searching, was introduced by ESA/IRS in Dec. 85. TARGET, which employs partial match probabilistic retrieval was introduced by DIALOG in Dec 93. 6 subject searches were carried out on databases available on both Dialog and ESA/IRS to compare TARGET and QUESTQUORUM with Boolean searching. Outlines the main advantages of these tools, and their disadvantages. Suggests when their use may be preferable
