What is the method used by Redis Bloom filter?

The main steps for using a Redis Bloom Filter include the following:

1. Create a Bloom filter: Use the command BF.RESERVE to create a Bloom filter in Redis, where is the key name of the Bloom filter, is the expected false positive rate, and is the initial capacity of the Bloom filter.
2. Add elements: Use the command BF.ADD to add the element to the Bloom filter.
3. Check if an element exists: Use the command BF.EXISTS to verify if the element is present in the Bloom filter. If the result is 1, the element may exist; if it is 0, the element definitely does not exist.
4. Adding elements in bulk: use the command BF.MADD … to add multiple elements to the Bloom filter at once.
5. Batch check if elements exist: Use the command BF.MEXISTS … to check multiple elements if they exist in the Bloom filter. It returns a list where each element corresponds to each element in the input list, returning 1 if the element may exist, and 0 if the element definitely does not exist.
6. Remove a Bloom filter: Use the command DEL to delete the Bloom filter and its related data.
