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 http://lucene.apache.org/java/3_4_0/queryparsersyntax.html#Escaping Special Characters and QueryParser.escape(String s). -- Ian.
