This add-on is a native library developed in C++, and a considerable boost to the capacities of Open Search Server. Thanks to an optimised native code, OSS Engine gets exceptional performances from Open Search Server. Enhancements include:

* Pertinence personalisation offers gigantic possibilities
* Document indexation is faster by an order of magnitude
* Improved response times
* Heightened number of possible simultaneous queries

OSS Engine works as an add-on to Open Search Server on Linux, Solaris, Windows 20xx/XP/Vista and MacOS X whether in 32 or 64 bits. It is distributed through the attribution of a proprietary licence.

Features:

• Multi-languages indexing. Documents can be indexed in sixteen languages - Chinese, Danish, Dutch, English, Finnish, French, German, Hungarian, Italian, Norwegian, Portuguese, Romanian, Russian, Spanish, Swedish, Turkish.
• Multi-lingual analysers slice sentences into words, then run lemmatisation algorithms on words based on the document's language (singular/plural, gender, conjugated verbs, etc.)
• The crawlers go through web sites and file systems to rapidly and easily build your index.
• Numerous document formats are supported, such as XML, HTML/XHTML, Adobe PDF, Microsoft Word, PowerPoint, OpenOffice, etc.
• The web interface is built around the power offered by the Zkoss framework. It runs with the main Ajax browsers. This RIA-type interface is as comfortable to use as that of a heavy client.

• Quick integration thanks to an XML interface via HTTP queries (XML over HTTP).
