To accurately search for content on Douyin, you can try the following methods:

1. Clearly search for keywords. When entering keywords in the search box, try to use specific and descriptive words, and avoid using vague and broad words. This will help narrow the scope of search results and improve the accuracy of the search. For example, if you want to find a video of a certain celebrity, it is recommended to search using the celebrity's full name instead of a nickname.

2. Use the filtering function. After getting the preliminary search results, you can use the filtering function provided by Douyin to filter according to the topic, length, release time and other conditions of the video. This can further narrow the scope of search results and find more accurate content. For example, you can set the filtering condition to the topic of "funny" and limit the video length to no more than 1 minute.

3. Make good use of the "hot" and "latest" functions. There are usually some popular or newly released videos on the Douyin search results page. These videos are usually calculated based on indicators such as the number of clicks and likes, and have a certain reference value. You can try clicking on some of these videos to see if they meet your search needs.

4. Try different search options. Douyin's search box usually provides some search options, such as "General", "Video", "User", etc. These options will filter and sort the search results differently. You can try to switch different options to see how they affect the search results.

The above are some methods for accurately searching for content on Douyin. Remember, effective search requires patience and trial and error. You may need to try different keywords and filter conditions many times to find the results that best meet your needs.
