OpenSearchServer is a powerful, enterprise-class, search engine program. Using its Web user interface, crawlers (Web, file, database, etc.), and REST/RESTFul API, you can integrate advanced full-text search capabilities into your application.
This release adds many user interface improvements and new features. A new PDF viewer is able to highlight searched keywords on PDF pages. This powerful new feature also supports scanned PDF documents (OCR). Visio and Publisher documents are supported, and RSS feeds are indexed. A new report module provides information on the most often-searched words and which words don't return a document. Information about users and groups are extracted while browsing CIFS/SMB and FTP repositories.
