    Abstract
    Because the WWW is a dynamic collection of information, the Web search tools (or 'search engines') that index the Web are dynamic. Traditional information retrieval evaluation techniques may not provide reliable results when applied to the Web search tools. This study is the result of 10 replications of the 1996 classic Ding and Marchionini Web search tool research. It explores the effects that replication can have on transforming unreliable results from one iteration into replicable and therefore reliable results following multile iterations
