## Describe the bug Use a certain word to find the problem. But the result is not what I want. I used spaces to split different words. But it didn't work. For example, the question I found did not have the word “any” in it. ### To Reproduce <img width="1429" alt="image" src="https://github.com/apache/incubator-answer/assets/135837370/307a3378-37bc-484b-9171-84a82fd2a5de"> <img width="1340" alt="image" src="https://github.com/apache/incubator-answer/assets/135837370/2d8868c1-c86d-4597-8661-72aecada01a6">
