Distributed Search Engine for an IaaS Based Cloud

Cloud based online storage enables the storage of massive data. In these systems, a full text search engine is very important for finding documents. In this paper, we propose a distributed search engine suitable for searching a cloud. In our previous work, we developed a distributed search engine, the cooperative search engine (CSE). We now extend the CSE to search clouds. In a cloud, elasticity and reliability are important. We realize these by employing consistent hashing for distributed index files in the cloud. In this paper, we describe the improved CSE architecture and its implementation for a cloud search.
