An Efficient Multi-Keyword Search Scheme using Logical Operations in Cloud Environment

Cloud computing is growing incredibly, in recent era, in effective manner. Because of its huge storage capability, data owner can feed the information as an outsourcing and cloud server provides that data for the users on demand. While the public user is utilizing the data through the cloud server, there found lot of issues. The proposed method uses multi keyword search scheme to improve search scheme over the cloud. This proposed scheme has three major tasks, first is to generate the relevance score based on the term-frequency; second task isto accomplish the index depends on the correlated words from the content by using the classified sub-dictionaries technique. This sub-dictionaries technique is applied to attain higher potency and to enhance quick accessing of cloud data. Finally, the multi keyword search scheme consists of Boolean techniques such as AND, OR, NOT is applied. By using this technique the information can be retrieved from dataset in robust manner
