You could write a custom analyzer that drops stopwords but adds an extra 1 to the "positionIncrement" property for the next valid Token after each omiited stop word.
This would retain the benefit of removing stopwords from your index and yet prevent your example phrases matching (because the remaining words are not recorded as being directly next to each other) Cheers Mark ----- Original Message ---- From: Sirish Vadala <[EMAIL PROTECTED]> To: java-user@lucene.apache.org Sent: Tuesday, 18 December, 2007 5:10:19 PM Subject: RE: Phrase Query Problem Yes...
