Block range limitaion

When considering the block range, it is important to note that the response size for the getFilterLogs and getLogs methods varies accordingly. Specifically:

• Block range exceeding 50K: Unavailable for querying.

• Block range less than or equal to 100: Experiences no limitation on response size.

• Block range falling between 100 and 50K: At most, 50K records will be provided in the response.
