Technical Overview

The XTF system is divided into four components:

1. crossQuery: The front-end to the collection search system.
2. dynaXML: Interface to individual documents.
3. Text Engine: Used by crossQuery and dynaXML to perform text searches.
4. Indexer: Full-text indexer based on Lucene.

The following diagrams give a general overview of how documents are indexed, stored, queried, retrieved, and displayed using XTF:
