Search filters are tools that help users narrow down their search results based on specific criteria. For example, when looking for products online, filters can include options like price range, brand, or customer ratings. This makes it easier to find exactly what you need without sifting through irrelevant items. In addition to shopping, search filters are commonly used in databases and search engines like Google or Amazon. Users can apply filters to refine their searches by date, location, or content type, ensuring they receive the most relevant information quickly and efficiently.
