Embodiments of the invention relate to a method for retrieving event data. The method includes receiving, by an event management device, an event query requesting event data corresponding to a filtering parameter, the filtering parameter being a non-indexed database parameter of an Internet Protocol database (IPDB). The method includes generating, by the event manager device, a Bloom filter value based upon the filtering parameter included in the event query. The method includes comparing, by the event manager device, the Bloom filter value with a Bloom filter index entry of an index file of the IPDB, the index file corresponding to the requested event data, the Bloom filter index entry indicating existence of the filtering parameter as part of the IPDB and reading, by the event manager device, the entry from the index file database when the Bloom filter value matches the Bloom filter index entry.
