12.7.1 Know and Know Simple Queries

The intent of a Know query is to find information or explore a topic. Users want to Know more about something.

Know Simple queries are a special type of Know query. Know Simple queries seek a very specific answer, like a fact, diagram, etc. This answer has to be correct and complete, and can be displayed in a relatively small amount of space. As a general rule, if most people would agree on a correct answer, and it would fit in 1-2 sentences or a short list of items, the query can be called a Know Simple query.

Know Simple queries may be questions such as [how tall is barack obama]. Frequently, Know Simple queries do not have question words. For example, [barack obama height] has the same user intent as [how tall is barack obama], but is not in a question format.

Most queries are not Know Simple queries, such as:

● Broad, complex, and/or in-depth informational queries that do not have a short answer
● Ambiguous or unclear informational queries
● Informational queries on controversial topics
● Informational queries with no definitive “right answer”
● Queries where different users may want different types of information, or different sources of information
● Queries where users want to browse or explore a topic
● Queries where users want to find inspiration or ideas related to a topic
● Queries where users are seeking personal opinions and perspectives from real people

Here are some examples where the Know Simple query asks for a simple fact, which can be answered correctly and completely in a small amount of space, and the Know query answer is more complex.

Know Simple Query	Know Query	Explanation
[weather]	[how do people predict the weather]	The query [weather] may seem like a broad information query, but most people likely have a fairly simple informational need: to find the current or upcoming temperature, and the chance of local weather events such as rain or snow. Therefore, consider queries like [weather], [weather today], [weather tomorrow], [weather this week] to be Know Simple queries. In contrast, the Know query is a broad information query and different users may be looking for different things.
[what is a bowl cut]	[hair styles for men with round faces]	Users who issue the Know query are likely seeking inspiration for a new hair style. There is no definitive right answer for this query.
[what is the social security retirement age]	[retirement planning]	The Know query is about a complicated and situational topic. Many users would issue this query with the intent of broadly exploring the topic, and different users would be better served by different information.
