Which symbol is NOT used to narrow search results?

The symbol that is not used to narrow search results is the percentage sign (%). When conducting searches, particularly in search engines like Google, there are specific symbols that can be used to refine results for more targeted information.

The plus sign (+) is typically used to ensure that a certain word or phrase is included in the search results, effectively narrowing the results to those that contain that specific term. The minus sign (-) serves to exclude certain words from the search results, which also helps to narrow the results by removing unwanted topics or terms. The asterisk (*) acts as a wildcard that can represent one or more unspecified words, enabling broader searches while still allowing some level of specificity depending on the context.

In contrast, the percentage sign does not serve any function in search operations related to refining or narrowing down results. Its presence in search queries will not yield any beneficial outcomes in refining the search parameters or results. Understanding the functions of these different symbols is crucial for effective online searching and retrieval of relevant information.
