A commercial information search system includes an information center and
a search interaction platform. The information center includes an
information database storing a plurality of web data characterized by a
plurality of languages respectively, wherein the information center is
adapted for a user accessing through a public communication network. The
search interaction platform is communicatively linking with the
information center, wherein when a search request with a selected
language is sent to the information center through the public
communication network, the information center sorts out the web data to
match with the search request to generate a search result based on the
web data with the selected language, so as to eliminate unrelated web
data with other languages being translated into the selected language to
be shown in the search result.
