I'm not sure which website or platform you're referring to. However, generally speaking, if the search function of the Midnight Book Chase website or platform could not be used, there might be the following possible reasons: 1. Network problem: It may be because the network connection is unstable, causing the search function to not work properly. You can try to restart your browser or try other ways to connect to the Internet. 2. Search restrictions: Some websites or platforms may limit the search range or search keywords of novel searches to prevent too many search results from interfering with users 'browsing. 3. copyright protection: some novels may have copyright protection, which means that the relevant novel content can only be found if the website or platform has copyright. If you still can't find the novel, try searching on other search engines or platforms or contact the customer service of the website for further help.
