Open Directory version by Bryn Dole was released in February, 2001. He wrote in a message to the ISearch mailing list:
This version of search is much smaller, much faster, and much simpler than the original Isearch. The Open Directory Search does not run on Windows. It currently only supports Linux and Solaris. I've included some sample scripts for parsing the Open Directory RDF data so that you too can build your own Internet search engine. Provided you have a few Sun E4500s lying around. ;)
I gave it a pre-1.0 release number because of the newness of the release, not the code. I figure I'll go through a few iterations in the packaging, at which point I'll up the release number to 1.0. If more than a few people start making suggestions, I'll get motivated to put the source up on the mozilla.org CVS server.
This version of Open Directory Search understands the UTF-8 encoding, and interprets individual Chinese (and Japanese) characters as "words" allowing searches to be done on individual Chinese characters and combinations of characters. The initial data that is indexed and the searches have to be in UTF-8 for this to work. It will also work for other non-UTF-8 charsets, but may require spaces or punctuation between words for search to work properly.
