Although dcupl offers a wide range of impressive features for searching and filtering your data, it currently doesn't address fuzzy search in its core. Fortunately, there are excellent third-party libraries available that specialize in this area and can be integrated into your application quickly.
Generally, using third-party libraries with dcupl is straightforward. Simply query the necessary data and pass it to the library. The result may include the key of your dcupl data entry, allowing you to use query.many([...]) to retrieve the results again.
