Topics are order-dependent. A transaction with a log with topics [A, B] will be matched by the following topic filters:
- [] "anything"
- [A] "A in first position (and anything after)"
- [null, B] "anything in first position AND B in second position (and anything after)"
- [A, B] "A in first position AND B in second position (and anything after)"
- [[A, B], [A, B]] "(A OR B) in first position AND (A OR B) in second position (and anything after)"
