A retrospective method for the performance comparison of Boolean and best-match queries is introduced. The method is based on the interactive optimisation of queries by a group of test searchers using a query performance analyser. The case experiment focused on comparing the maximum effectiveness of Boolean exact-match queries, and structured and unstructured best-match queries. The experiment verified the problems in maintaining precision of Boolean queries at high recall levels. Interesting similarities were also observed between structured and unstructured best-match queries giving new light on the results of earlier studies. The case experiment showed that the proposed evaluation method yields more elaborated results in comparisons than earlier query-centred methods.
