1. A computer-implemented method for identifying one or more relevant documents, comprising: generating, by a computer, a filter for identifying a relevant document based on an initial relevance rule related to a set of documents; applying, by the computer, the filter to the set of documents thereby identifying a subset of relevant documents; receiving, by the computer from an assessor, the subset of relevant documents comprising an identification of key information; generating, by the computer, an updated relevance rule based on the key information and the initial relevance rule; generating, by the computer, a query based on the updated relevance rule for identifying relevant documents within the set of documents; and outputting, by the computer, the set of documents within which the relevant documents have been identified.
