This feature has been used for a long time to replace the article blocking word with regular expressions. Because there is no pressure during use, its performance has not been optimized. At the leader's request today, I tested and improved the performance, and found that the improved performance has increased by more than 100 times! It took more than 130 milliseconds to replace an article. Now it only takes less than 1 millisecond! The main difference is the regular expression generation and the
