The goal of a search process is to identify a set of documents that together can satisfy an information need. Subtasks include refinement of the searcher's understanding of their need, refinement of the expression of that need as a query, and recognition of relevant documents. Automated components of search systems typically accomplish only portions of the required task, leaving the searcher to assess factors (e.g., veracity and completeness) that would be difficult to detect by automated means. Searchers with limited proficiency in languages in which the document are written will require translation support to accomplish information need refinement, query reformulation, and relevant document recognition.
