Comparisons
[Note: March 12, 2001 Northern Light Technology announced the re-launch of
the Hungarian national search engine, Vizsla. The Web search engine had
previously operated under the name of Alta Vizsla and was powered by
search software from Alta Vista. Following a lengthy investigation and
analysis, MATAVnet selected Northern Light to provide the Web crawling,
indexing and search software. MorphLogic, also of Budapest, a specialist
in linguistics programs, worked closely with Northern Light to provide the
Hungarian language analysis software. The re-launched service provides
access to a larger database - currently over two million pages, faster
response time, more frequent updating and more precise searching. This
engagement represents the first time Northern Light has developed a
non-English language version of its search software.]
