Increase the maximum number of records in getRecords method?

Right now we are only able to obtain 200 records from any module using getRecords. Reading through the forum I see there used to be a getAllRecords method, but that is not in the documentation anymore. We would like to be able to specify, say, fromIndex = 1, toIndex = 1000. Is this possible?
