Open Search Server for Mac

From Open Search Server:

Open Search Server (OSS) is a search engine software developed under the GPL v3 open source licence. Built using the best open source technologies available, Open Search Server is a stable, high-performance piece of software. It is both a modern search engine and a suite of high-powered full text search algorithms.

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.
