# Search and Filter Knowledge

Sometimes, you might need to search a knowledge. Maybe it’s because you have a lot of knowledge. If you are looking for knowledge manually one by one, it will take a long time. Therefore, you need a search knowledge feature to make it easier for you to find knowledge. On the FAQ Knowledge page, you can search knowledge based on *title* and *question*.

After reviewing the search results from the above, you may want to filter the knowledge page to find the best results. In the 3dolphins system, you can filter knowledge by *‘created’, ‘title’* and *‘last modification’* which you can filter by *ascending* or *descending*.
