Qizx, a native XML search engine

What Qizx is:

To put it simply, Qizx allows you to store and index XML documents, of any type and size, and to perform searches and transformations on stored documents with great speed and power.

Qizx is an embeddable Java engine: this means that it can be the core of a server, or it can be directly embedded in a standalone application.

Qizx is based on standards: it fully supports the XQuery language and its extensions XQuery Full-Text and XQuery Update.

Storing documents in Qizx is easy: no DTD or Schema are required, Documents are indexed automatically.

Writing XQuery queries for Qizx is easy: it uses its indexes intelligently. With Qizx, there is no need to define and tweak indexes or queries endlessly to get the best performance.

• What is the difference between Qizx and a Native XML Database ?

  Not a big difference: Qizx can do all what Native XML Databases do. The main difference is that NXDbs are generally optimized for updates, and often offer relatively poor search speed. Qizx is the opposite: it is optimized for high querying speed (hence the term 'search engine') but not for intensive updating of XML data.

• What is the difference between Qizx and a full-text engine like Lucene ?

  A full-text engine can only perform full-text queries, using proprietary syntax. Qizx fully supports the standard XQuery language and its powerful XQuery Full-Text extension. With XQuery + Full-Text it is possible to combine full-text search criteria and queries based on values of any XML element or attribute. This offers unprecedented search power and flexibility, which Qizx still enhances by also allowing queries on metadata associated with XML documents.

• Evaluation

  Qizx is available as Free Engine Edition, which has all the features of the commercial edition, but is limited in terms of the maximal size of a database (approximately 1000 megabytes of source XML).

  You can evaluate Qizx without size limitations by requesting an evaluation key, valid for three weeks.

• Qizx/open

  The Open Source version of Qizx has been available since 2003. QIzx/open fully implements the XML Query language, but has no persistent storage and no indexing capabilities. It is in fact a component of the complete Qizx product.
