Public cloud is now very quick growing trend for storing user’s data. Most of the users now a day’s placing their personal and professional data on the cloud. Cloud computing has won over a lot of interest from different areas since it provides Systematic resource management, Economical cost , Fast deployment, scalability, availability, low cost service over traditional storage solutions. The imaginative in cloud computing has motivated the data owner to deploy their data from local sites to profitable public cloud for enormous elasticity and profitable savings. At the same time secrecy of remotely stored data on untrusted cloud server is big responsibility. In order to diminish these responsibility of sensitive data such as E-mails, reports, personal information are outsourced in encrypted form using encoding system. The security concerns in cloud computing motivate the study on secure keyword search. The search techniques which are used on plain text cannot be used over encrypted data. The existing solutions supports only identical keyword search, semantic search is not supported. As we don’t want to disclose neither keyword from query nor query pattern, we have developed fully privacy preserving system by encrypting search pattern as well as secret key. Indexing has been developed to build an index of keywords from documents. Index will be used to retrieve documents in response to search query by using the principle of keyword matching. This paper has analyzed and implemented Lucene indexing algorithm. Ranking of the results has been developed so as to improve the search result correctness as well as to enrich the user searching experience.
