You may need to rebuild the index with 1.3. Buried in the Changes document it says that you have to rebuild the index with 1.3, because the scoring was changed internally.

I also changed the default operator to AND. It seems work fine but actually the search results from Lucene 1.3 are not as good as the results from 1.2 (same index and same query) even the query a.. top documents from 1.3 are not as good as the ones from 1.2 b.. the top document score from 1.3 are almost the same and 1.2 has better score system. Any idea about this? Is there any way I can achieve the same search quality within 1.3?
