ABSTRACT: With the arrival of cloud computing, data owners can outsource their complex data from local systems to the commercial public cloud .Storing data on cloud enables them to access their data from anywhere by using any system. The main advantage of cloud computing is data service outsourcing.It allows data owners to store their documents in the public data centers by economically saving their capital investment towards data management. But for protecting data privacy, sensitive information must be encrypted before storing them to cloud.Encrypting the documents before storing them to cloud outmoded traditional data utilization which focuses on plaintext keyword search. Today’s main challenge is to enable searching over encrypted cloud data. Since cloud contains large number of data users and documents, it is necessary to allow multi-keywords in the search request and return documents in the order of their relevance to these keywords. The main aim is to make effective data access in the public cloud storage by improving various searching techniques, thereby, increasing the data utilization. In this survey, an attempt is made to study various searching techniques over encrypted cloud data.
