A method for scaling of indexing data D=(dn, n=1 to N) of a multimedia document having the following steps: (a) at the time t, in grouping the data D in distinct and consecutive groups Dj respectively sized n'j, j varying from 1 to J and in respectively scaling each group Dj by a value d'j according to at least one determined scaling method C and in storing the data D'=(d'j,j=1 to J) thus obtained, (b) subsequently, at the time t'>t, when the number of data resulting from the previous scaling is too great, in grouping the data D' in distinct and consecutive groups D'k respectively sized Jk, k varying from 1 to K and respectively scaling each group D'k by a value d''k according to a rescaling method C' compatible with the scaling method C in such a way that each of the data d''k is equivalent to that obtained by applying the scaling method C directly to distinct and consecutive groups of data D respectively sized n''k, n''k being the sum of the n'j values of the group D'k and in storing the scaled data D''=(d''k, k=1 to K).
