<p>A non-transitory, computer readable storage medium storing a program for a computer being capable of accessing a group of nodes having divided-data structures obtained by dividing a data structure having a transposed hierarchical bloom filter of a hierarchical bloom filter and sets of data blocks by a predetermined bit width, wherein the hierarchical bloom filter has h-stage bloom filter arrays each having a bit width of s, the hth-stage bloom filter array having bits indicating false positives or negatives and the pth-stage bloom filter array having n=d[h-(p-1)] bloom filters (where 1≰p≰h) each having a bit width of m=s/d[h-(p-1)] (where d indicates a division number for the hth-stage bloom filter array), the transposed hierarchical bloom filter is obtained in the bloom filters in the bloom filter array, and the set of data blocks corresponds to the first-stage bloom filter array of the hierarchical bloom filter.</p> |
