Thanks Danny. I tried the first option with just 2 documents loaded in the database. Both have exactly one occurrence of the word "life". One has it in the "title" element and the other in the "desc" element. Now, when I search for "life" using the new search API (sample code in earlier mail), both documents get returned with exactly the same "score" and "fitness". I have tried setting weights starting from 2.0 to 20.0 for "title" and made sure the documents are reloaded / re-indexed, but still no change.
Thanks for your help.
