Creating a search engine involves understanding key components such as web servers, data ingestion, indices, and search engine results pages (SERPs), which collectively function like a librarian helping users find information efficiently. The process, as outlined by the Elastic Platform Team, includes defining search requirements, crawling the web for data, storing collected information, indexing the data, and optimizing search results. Elastic's tools facilitate each step, from data ingestion with its web crawler to leveraging machine learning for enhanced relevance, offering developers a comprehensive suite to build effective search engines tailored to specific needs.
