The default page sorting algorithm in Nutch which is open source search engine is TF/IDF algorithm, but it's difficult to meet the demand of music page sorting. The paper presents a new page sorting algorithm bases on BM25 model for music users. According word count and keyword frequency in music web pages, the pages whose keyword frequency is high and text size is long such as music home page, can be sorted at or near the top, and other music pages are low in sorting. The experiment proved that the new algorithm bases on BM25 model is better to meet demand of music page sorting than TF/IDF algorithm for music users.
