If I create a nostr filter with two tags, it make an OR instead an AND? There is a way to make this work as AND and not as OR? For example:

{
"kinds":[1],
"#t": ["meme", "bitcoin"]
}

This will return events with "meme" and/or "bitcoin", if I want only event with both I must code a custom filter, is that right?
