Amberfish is general purpose text retrieval software, developed at Etymon by Nassib Nassar and distributed as open source software under the terms of version 2 of the GNU General Public License GPL. Its distinguishing features are indexing/search of semi-structured text i.e. both free tex and multiply nested fields, built-in support for XML documents using the Xerces library, structured queries allowing generalized field/tag paths, hierarchical result sets XML only, automatic searching across multiple databases allowing modular indexing, TREC format results, efficient indexing, and relatively low memory requirements during indexing and the ability to index documents larger than available memory. Z39.50 support is available. Other features include Boolean queries, right truncation, phrase searching, relevance ranking, support for multiple documents per file, incremental indexing, and easy integration with other UNIX tools, The architecture is also designed to permit proximity queries; however, they are not fully implemented at present.
