This package includes the alvis filter which uses libxslt1 to transform XML records by XSLT into XML indexable records. DEPRECATED, better use the libidzebra-2.0-mod-dom indexing filter. . IDZebra is a high-performance, general-purpose structured text indexing and retrieval engine. It reads structured records in a variety of input formats (eg. email, XML, MARC) and allows access to them through exact boolean search expressions and relevance-ranked free-text queries.
