Abstract
In an automatic electronic discovery search tool, documents can be clustered into a cluster hierarchy using data contained in a first field of the documents. One of more levels of the cluster hierarchy are merged. Merged clusters are further clustered using data contained in a second field of the documents. The first field and second field may be determined by the signal-to-noise ratio of the data contained in the fields. Clusters may be filtered or used in a document review tool.
