Which search query type indicates a valid result according to search standards?

The first option, which is "Miami wikipedia.org," indicates a valid result according to search standards because it specifically directs to a well-known source of information, namely Wikipedia. Search standards often prioritize established and authoritative sources for informational queries, and since Wikipedia is widely recognized as a credible source for general knowledge, this query type effectively signals the user’s intent to find specific data or information about Miami.

In contrast, the other options represent broader or less specific types of queries. While "Miami videos," "Miami restaurants," and "Miami faq" can also yield valid results, they do not explicitly point to a specific, authoritative source, which makes them less aligned with standard practices towards identifying a clear, reliable informational output.
