Tushar Joshi works as a software architect and JUG leader at Persistent Systems. He is also a member of the NetBeans Dream Team. The document discusses the key components and processes of how a basic search engine works, including crawlers that scan web pages and build an index, sorting and ranking search results based on relevance metrics like page rank, and caching results for faster retrieval rather than conducting real-time searches. It also provides some background on the origins and meaning of the name "Google".
