Limiters are tools or techniques used to narrow down search results or data sets, making it easier to find specific information. They can include filters like date ranges, geographic locations, or specific categories. For example, when searching for articles on climate change, a limiter might restrict results to the last five years or to studies conducted in North America. In digital databases and search engines, limiters help users refine their queries. By applying these constraints, users can avoid overwhelming amounts of information and focus on the most relevant results. This is particularly useful in academic research or when looking for specific products online.
