Abstract
The use of variety generation techniques in the production of fixed‐length degenerate representations for search terms is compared with methods based on division‐hashing. For files of words taken from INSPEC data, the latter perform better, almost certainly because of dependence between assignments of symbol sets. Attempts to overcome the problem produced no real improvement, possibly because the decrease in dependence was accompanied by an increased skewness in the distribution of symbols.

Abstract
The use of variety generation techniques in the production of author‐title search codes for files of monograph records is compared with methods based on division hashing. The latter perform better, and evidence is presented to suggest that the reason for this is the lack of statistical independence between the assignments of variety generation symbols to different parts of a field in the record.
