| Abstract: | The calculation of Lucene similarity,which makes supreme text for words similarity accessible to the users,is an essential part of Lucene search engines.Its performance directly affects the final score,which is achieved by means of scoring formulas.Accordingly,improvement should be made on scoring formulas algorithms so that the scoring formulas for Lucene similarity can accurately present information for the users. |
