Web search engines provide easy access to a wealth of open access information but depend for their optimal use upon careful selection of search terms in order to return a high proportion of relevant information. Generally, this implies a clear association between the meaning of the chosen search expression and the information needs of the searcher. In contrast, this paper considers a scenario in which the searcher may wish to retrieve information without making their information requirements transparent. We argue that careful choice of non-optimal search strategy can facilitate retrieval of relevant information in a covert fashion that conceals the searcher’s intention by ensuring return of a majority of irrelevant search hits. This suggests the viability of covert search and raises issues regarding surveillance and counter-surveillance.
