If you have Tomcat it defaults to iso-8859-1 as character encoding i
think, try to recode your input to utf-8 before feeding it to lucene.
s = new String(s.getBytes(),"UTF-8");

Thanks for your reply :)
I have already debugged the input string s. As I said
before, s is a string which is sent by client through
the "doPost()" method of servlet
At first, I thought that the analyzer is the cause of
the problem and that it lowercase all leters. However,
then, I have also known that WhitespaceAnalyzer do
not do that.
Therefore, I changed my mind and I wonder if the
problem is resulted from the servlet technology. Yet,
when I debugged the input string s I saw that before
the method, string s was still indentical to what was
sent from client.

Sounds very strange, have you debugged the input

it come from?

Dear all,
I really appreciate your work on Lucene. It is
apparently a helpful API for my project on indexed
Document searching. On the whole, It works
properly
and perfectly.
However, there is a problem when I try to query
what I
have indexed with the keyword received through
internet using Servlet technology. The specific
problem is the followings:
// This is the method I use to parse my query
Query myQuery = QueryParser.parse(s,
"NamedEntity",
analyzer);
with s is the query string received from client,
analyzer is the WhitespaceAnalyzer and the version
of
Lucene is lucene-1.4-final.jar
Before this method, the value of s is "Chua_Huong"
with C and H are uppercased letters
After this method myQuery = NamedEntity:chua_huong
with c and h are lowercased
Yet, if I type the String "Chua_Huong" directly
onto
the first argument (the position of s),
Query myQuery =
QueryParser.parse("Chua_Huong","NamedEntity",analyzer);
After the method, myQuery = NamedEntity:Chua_Huong
with C and H are still uppercased letters.
What happened with this?
Please if you can, reply to my problem as soon as
possible.
I would be most grateful for your helpfulness!
Thanks in advance
Sincerely yours
Thanh Hai
