Abstract

Experiments in online searching behaviour have failed to explain the phenomena they were designed to study. An examination of the variables used in research to data finds the most commonly used independent variables are searcher characteristics. Search-process and search outcome variables are the most commonly dependent variables. The search process variables are inadequate because they are situational and subject to constant change. Significantly, these variables measure the cost of a search rather than the intellectual processes involved in answering a request. While these experiments could support the discovery of the 'productive searcher', they cannot uncover searching behaviour. Only in-depth analyses of the search process itself can lead to productive research

Abstract

The model of operationalist and conceptualist searching styles describes searching behavior of experienced online searchers. It is based on the systematic observation of five experienced online searchers doing their regular, job-related searches, and on the analysis of 10 to 13 searches conducted by each of them. Operationalist searchers aim at optimal strategies to achieve precise retrieval; they use a large range of system capabilities in their interaction. They preserve the specific meaning of the request, and the aim of their interactions is an answer set representing the request precisely. Conceptualist searchers analyze a request by seeking to fit it into a faceted structure. They first enter the facet that represents the most important aspect of the request. Their search is then centered on retrieving subsets from this primary set by introducing additional facets. In contrast to the operationalists, they are primarily concerned with recall. During the interaction they preserve the faceted structure, but may change the specific meaning of the request. Although not comprehensive, the model aids in recognizing special and individual characteristics of searching behavior which provide explanations of previous research and guidelines for further investigations into the search process
