If you escape the character + or #, the sentence:
"I know java + c++" would not skip +, furthermore, it breaks query parsing,
where + is reserved.

Try WhitespaceAnalyzer for both indexing and searching.
On search-time you may also need to escape "+", "(", ")" with "\".
"#" shouldn't need escaping.

Do I have to escape during indexing too?

Hi
Escaping should work. See
http://lucene.apache.org/java/2_4_1/queryparsersyntax.html and
QueryParser.escape(). And you need to be sure that your analyzer
isn't removing the plus signs and that you use the same analyzer for
indexing and searching.

Hello,
I'm trying to search for the terms like c++ but the parser is stripping off the
++. I tried escaping the ++ with slashes but it's still stripping it off. I
could replace + with "plus", is that the best way to do it? How come escaping
isn't working?
thanks

Thanks everyone. I appreciate the help.
I think I will write my own tokenizer, because I do not have a
predefined list of words with symbols.
I will modify the grammar by defining a SYMBOL token as John suggested
and redefine ALPHANUM to include it.

This isn't ideal, but if you have a defined list of such terms, you
may find it easier to filter these terms out into a separate field
for indexing.

I don't think there is a simpler way. I think you will have to modify
the tokenizer. Once you go beyond basic human-readable text, you always
end up having to do that. I have modified the JavaCC version of
StandardTokenizer for allowing symbols to pass through, but I've never
used the JFlex ve
Hello:
I have a problem where I need to search for the term "C++".
If I use StandardAnalyzer, the "+" characters are removed and the
search is done on just the "c" character which is not what is
intended.
Yet, I need to use standard analyzer for the other benefits it provides.
