launched Beta version with a new search technology called
Semantic Key.  Semantic Keys enable users to query with a conceptual keyword
(or a keyword with a special meaning, hence the term Semantic Key) in order
to find instances under the concept, e.g. price → $5.95 or €200, color →
red, yellow, white.  For example, “price: a pound of apples”, “color:
ferrari”.  With initial 500 Semantic Keys at the Beta launch, Lexxe
became the first search engine in the world to offer this unique and useful
search technology to the users.

In human communication, Semantic Keys are common in questions and
information exchange.  Likewise, they could be a useful tool for search
engines between users and internet information, particularly when dealing
with unstructured data.

Lexxe Beta version also supports normal keyword search.
