You can achieve pretty much anything by customizing parsers and
tokenizers but for your simple case I'd just use String.split() and
add the phrases one by one. Something like
Document d = ...
String[] phrases = sentence,split(",");
for (String phrase : phrases) {
d.add(new Field("phrase", phrase, ...);
}
I think that would achieve what you want.
On special characters. see

Special Characters and QueryParser.escape(String s).
