Nuxeo Platform provides a framework and set of components to address document management and collaboration needs, including metadata/taxonomies, versioning, lifecyle management, workflow, relations, searching, reporting, transformation, auditing, and retention. Its flexible extension system, based on OSGi, allows developers to quickly configure and extend the platform by creating new components. Its default Web user interface, based on the JSF standard, uses AJAX to create a pleasant user experience. It can also be accessed by a rich client interface through the use of Web services, for instance using the Eclipse-based Nuxeo RCP rich client platform.
LogicalDOC is a Web-based document management system that is easy to use and learn. Its architecture leverages best-of-breed Java technology to achieve a powerful and flexible solution. It supports its users with a powerful search engine (Lucene), Web service interface (JAX-WS via CXF) compatible with .NET and PHP, versioning, annotation on documents, a WebDAV interface, importing and exporting from .zip files. Documents can be organized into hierarchical folders, searched using the integrated search engine, or browsed by Tag. The system is extensible thanks to the technologies used (Spring-Hibernate) and its plugin architecture.
Nariva is an application which aims to provide cross- platform, open API search functionality targeted at desktops. It uses Apache Lucene to perform the indexing and searching functionality and also exposes the Apache Lucene API as an XML-RPC service (provided using Apache XML- RPC). Files on the local file system are monitored using a sandbox component called Commons Virtual Filesystem (VFS). Nariva ties all these projects together to provide a simple, fast, cross platform, desktop search solution.
MKSearch is a metadata search engine that indexes structured metadata in Web documents instead of free text in the document body. The data acquisition system conforms to the Dublin Core metadata in HTML recommendations, and supports other application profiles, such as the UK e-Government Metadata Standard. It also indexes native RDF formats, including RSS 1.0. The system has five major components: a Web crawler, an HTML document validator and formatter, a set of custom indexers, an RDF storage and query system, and a public query interface, provided through a standard servlet container.
PIVIAU is a PHP/MySQL Web based gallery for pictures, videos, and audio that supports tags and EXIF. Albums and pictures have searchable tag, country, city, place, date, subject, and author.

YaCy is a search engine that anyone can use to index the Internet (WWW and FTP) or to create a search portal for others (Internet or intranet). The scale of YaCy is limited only by the number of users. and can index billions of web pages. In P2P mode it is fully decentralized. All users of the search engine network are equal and it is not possible for anyone to censor the content of the distributed index.
Xapian is a search engine library, scalable to collections containing hundreds of millions of documents. It's written in C++ with bindings for Perl, Python, PHP, Java, Tcl, C#, Ruby, and Lua. It is a highly adaptable toolkit that allows developers to easily add advanced indexing and search facilities to their own applications. It supports the Probabilistic Information Retrieval model and also a rich set of boolean query operators. Omega is a Web search application built upon the Xapian library. It can index a Web server's document tree (including HTML, PDF, OpenOffice, MS Word/Excel/Powerpoint/Works, WordPerfect, RTF, PS, etc.), or data exported from arbitrary sources (e.g. SQL databases).
