Built using the best open source technologies available, Open Search Server is a stable, high-performance piece of software.

Open Search Server is both a modern search engine and a suite of high-powered full text search algorithms.

Open Search Server runs on Mac OS X, Windows 20xx/XP/Vista, Solaris and Linux and a Java Virtual Machine.

Here are some key features of "Open Search Server":

· Multi-languages indexing. Documents can be indexed in ten languages – English, French, German, Spanish, Italian, Portuguese, Finnish, etc.
· 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™, 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.
· Easy configuration through a single XML file, which includes fields definition and the indexation options.
· Quick integration thanks to an XML interface via HTTP queries.

Requirements:

· Java
