That is to say, the search term is basically related to the context of the matching example sentence, and it is difficult for users to understand the usage of the search term from the reference example sentence

Therefore, the existing retrieval system cannot well meet the needs of users in foreign language learning or foreign language writing, and the user experience is poor.
