Hoss, If I limit the documents returned based on a score threshold (filter by score) will it be able to improve query performance? My intuition is it won't be able to because you will still have to calculate the score and then compare to the threshold. I know it may not be meaningful to do so based on the following explanation http://wiki.apache.org/jakarta-lucene/LuceneFAQ#head-912c1f237bb00259185353182948e5935f0c2f03 But it might work for me because the documents are not "natural language" but constructed following certain rules. If I really want to try this can you offer advice on the best way to implement score threshold in SOLR with minimum overhead? Appreciate if anyone can help Thank you Haishan
