Paper on Searching and Indexing Using Elasticsearch
International Journal Of Engineering And Computer Science, 2017 In today’s era, it is inconceivable to use traditional techniques / RDBMS to analyse the data as it is growing very quickly. Big data offers the solution for analysing large amount of data. Using technique of Elasticsearch, access to data can be made faster. Elasticsearch is a search engine based on Lucene.

Sherlock in OSS: A Novel Approach of Content-Based Searching in Object Storage System [PDF]
arXiv, 2023 Object Storage Systems (OSS) inside a cloud promise scalability, durability, availability, and concurrency. However, open-source OSS does not have a specific approach to letting users and administrators search based on the data, which is contained inside the object storage, without involving the entire cloud infrastructure. Therefore, in this paper, we
