Keyword Search
Keyword search is a fundamental information retrieval technique that involves finding documents or data based on specific words or phrases (keywords) entered by a user. It is widely used in search engines, databases, and applications to quickly locate relevant information from large datasets. The process typically includes indexing content, matching keywords against the index, and ranking results by relevance.
Developers should learn keyword search to implement efficient search functionality in applications, such as e-commerce sites, content management systems, or data analysis tools, where users need to filter and find information quickly. It is essential for improving user experience, handling large-scale data queries, and integrating with technologies like Elasticsearch or SQL databases for optimized performance.
