It is not necessarily true that all queries have only one intent. It is possible for a query to have multiple intents, or for the intent of a query to be unclear or ambiguous. For example, a query like "What is the weather like today?" could have a "know" intent (to find out the current weather) or a "do" intent (to decide whether to go outside or not). Similarly, a query like "Where is the nearest coffee shop?" could have a "website" intent (to find a website with information about nearby coffee shops) or a "visit-in-person" intent (to actually go to a coffee shop).
It is important to consider the context and the full range of possible intents when interpreting a query. In some cases, it may be helpful to ask the person who made the query for more information or clarification in order to better understand their intent.
