Hi
Can you provide a few examples of values of cpn that a) are and b) are not being found, for indexing and searching. You may also find some of the tips at http://wiki.apache.org/lucene-java/LuceneFAQ#Why_am_I_getting_no_hits_.2F_incorrect_hits.3F useful. You haven't shown the code that created the IndexWriter so the tip about using the same analyzer at index and search time might be relevant. -- Ian.
