A system for viewing and indexing mark up language messages, forms, and documents that have been stored in a document repository. The viewer and indexer can search the document repository based on any of a variety of search parameters, including any field of each message, form or document in the document repository. The viewer and indexer can automatically configure itself based on an input schema to create a user interface having search term options that can be selected to cause a search to be performed in the document repository (and/or mirrored and local repositories) containing messages, documents and forms created based on the same input schema.
