Most search engines rank results based on their “authority.”
Google for example, does this by the number of incoming high
quality links. Considering the fact that Wikipedia these days is
a source of high quality material, you find Wikipedia as the top
result of many search terms.
Google’s results these days are less than optimal. Spammers have
become quite sophisticated in their methods. Results are cluttered
with iframe results, shell websites, and other useless listings.
Wikiasari is a new venture by the same guys behind
Wikipedia. This is exactly what I’ve been looking forward to –
an engine that prefers Wikipedia over other sources.
The Times quotes Jimmy Wales, the founder of Wikipedia:
Google is very good at many types of search, but in many
instances it produces nothing but spam and useless crap. Try
searching for the term ‘Tampa hotels’, for example, and you will
not get any useful results.
The engine is built over Lucene, which is also behind
Beagle, the Free indexer for Linux desktops. They also say
the index will be released under the GFDL.
