The data on cloud computing is encrypted due to security concern or the factor of third party digging into it. As the consequence to this, the search over encrypted data becomes a complex task. The traditional approaches like searching in plain text cannot be apply over encrypted data. So, the searchable encryption techniques are being used. In searchable encryption techniques the order of relevance must be consider as the concern because when it is large amount of data it becomes complex as relevant documents are more in number. The authors have discussed the probabilistic Order Preserving Encryption (OPE) technique known as one-to-many OPE.
