Openfind is a leading enterprise search engine company in Taiwan, providing search to many government departments and corporations since 1998, scalable to over 50 million items in their standard licence. In addition to documents, it can index text and some numeric content from relational databases, off-loading the search and spreading the server load.
OES not only handles many languages including English, Arabic, Japanese, Simplified Chinese, and Traditional Chinese, the search interface and admin interface are also available in both versions of Chinese.
The program has a long list of useful features, including indexing by file system UNC. robot crawling, near-real-time indexing of structured XML, and full-featured ODBC database connectors. It can read text, HTML, PDF, Open Office and Microsoft Office file formats, and has an API for adding other formats.
Search features include Internet Query Operators ((+, -, "") and Boolean operators, including parentheses. Fields and metadata are searchable, and there are Search admins can use the web interface to edit the lists of stopwords, synonyms, autocomplete items and related terms -- in any character set. Relevance ranking includes term frequency algorithm and some heuristics, the results page UI is clean and simple, and some facets, including date and file type, are automatically generated.
There is a good suite of metrics and reports, and excellent documentation. While it's not the first search engine to have localized interfaces (Ultraseek, Autonomy and Google come to mind), OES is certainly worth a look.
