First, the shameless plug: my long-time friend, Jean-FranÃ§ois Racine published a book available both as hardcover and paperback. The title is “The Text of Matthew in the Writings of Basil of Caesarea”.
More seriously, and maybe he had told me about this, but he told me about this specialized word processor he uses, called Nota Bene. More interesting is a component of this word processor called Orbis. Specifically, Orbis generates vocabulary lists, as well as frequency of occurrence; and it allows you to define synonym lists to expand search capabilities.
