A method is provided for efficiently transferring records related to places of interest between two communicating vehicles in a V2V system without initially having to transfer full text records. A determination is made as to whether information stored in a memory of the vehicle is redundant with the respect to the other vehicle. A query request is transmitted from a first vehicle to a second vehicle containing specifics as to what records the first vehicle is seeking. Data satisfying the query request represented by global unique index numbers is hashed to determine the similarity between the data of the two communicating vehicles. The similarity is used to determine whether a full filtered set of global unique index numbers should be transferred to the second vehicle for determining which records are not duplicate records. Thereafter, the second vehicle wirelessly transmits to the first vehicle the non-overlapping data that satisfies the query request.
