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
