Hi,
This came up before, a while ago:
http://www.nabble.com/searching-for-C%2B%2B-to18093942.html#a18093942
I don't think there is an easier way than modifying the standard
analyzer. As I suggested in that earlier thread, I would make the
analyzer recognize token patterns that consist of words with prefixed or
postfixed symbols[1] Then you will receive tokens like "c++" or
"~/.file" in your token filter. You can then choose to pass them as
single tokens, or split them down further into two or more tokens.

[1] If you decide to try matching words with symbols in the middle, be
aware that the StandardAnalyzer already handles some examples of this,
such as e-mail addresses, so you may make something redundant.

to be detailed, I implemented a ftp search engine for campus students. I
have handle many different words including chinese words, as a result I
can't only use whitespaceanalyzer. My analyzer is now like this:
StandardTokenizer tokenStream = new StandardTokenizer(reader,
replaceInvalidAcronym);
tokenStream.setMaxTokenLength(maxTokenLength);
TokenStream result = new StandardFilter(tokenStream);
result = new LowerCaseFilter(result);
result = new StopFilter(result, stopSet);
result = new SnowballFilter(result,STEMMER);
StandardTokenizer is modified by me to split words like season09(like search
for friends season 09) to season" and "09"?
word "c++" is analyzed as "c".
I know i can modify the standardtokenizer to achieve my goal. But are there
any other neat methods?
