Exact matching is a technique used in various fields, including data analysis and information retrieval, to find items that are identical in value or content. This method ensures that only those items that perfectly match a specified criterion are considered, eliminating any variations or discrepancies. For example, in a database search, an exact match would return results that are exactly the same as the search term. In the context of search engines, exact matching can improve the relevance of search results. When users input a specific phrase, the search engine looks for pages that contain that exact phrase, rather than similar or related terms. This approach helps users find precise information quickly and efficiently.
